'Pulse-pounding' Sinclair McKay | 'Truly masterful' Damien Lewis | 'Who needs spy fiction, when fact can provide as thrilling a story as this?' Lindsey Hilsum The Spymaster of Baghdad is the gripping story of the top-secret Iraqi intelligence unit that infiltrated the Islamic State. More so than that of any foreign power, the information they gathered turned the tide against the insurgency, paving the way to the killing of ISIS leader Abu Bakr al-Baghdadi in 2019. Against the backdrop of the most brutal conflict of recent decades, we chart the spymaster's struggle to develop the unit from scratch in challenging circumstances after the American invasion of Iraq in 2003, we follow the fraught relationship of two of his agents, the al-Sudani brothers - one undercover in ISIS for sixteen long months, the other his handler - and we track a disillusioned scientist as she turns bomb-maker, threatening the lives of thousands. With unprecedented access to characters on all sides, Pulitzer Prize-finalist Margaret Coker challenges the conventional view that Western coalition forces defeated ISIS and reveals a page-turning story of unlikely heroes, unbelievable courage and good old-fashioned spycraft. 'Moving, visceral, utterly revelatory. A stunning tour de force by an author who has lived every word of it on the ground' Damien Lewis, author of Zero Six Bravo 'This compelling account of how Iraqi agents infiltrated ISIS takes us deep beneath the lurid headlines and into a sharply focused world of courage, ingenuity, terror and love' Sinclair McKay, author of Dresden 'In Margaret Coker's deeply reported, unputdownable account, the previously unknown Iraqi heros of the war against the Islamic State turn out to be braver than Bond and as subtle as Smiley' Lindsey Hilsum, author of In Extremis 'We all owe a debt of gratitude to the Falcons Unit for their important role in the fight against the most lethal terrorist group of our time' Anne Speckhard, Director of the International Center for the Study of Violent Extremism

A Cross of Iron provides the fullest account yet of the national security state that emerged in the first decade of the Cold War. Michael J. Hogan traces the process of state-making through struggles to unify the armed forces, harness science to military purposes, mobilize military manpower, control the defense budget, and distribute the cost of defense across the economy. President Harry S. Truman and his successor were in the middle of a fundamental contest over the nation's political identity and postwar purpose, and their efforts determined the size and shape of the national security state that finally emerged.

The success of the Allied codebreakers at Bletchley Park was one of the iconic intelligence achievements of World War II, immortalised in films such as The Imitation Game and Enigma. But cracking Enigma was only half of the story. Across the Channel, German intelligence agencies were hard at work breaking British and Allied codes. Now updated in paperback, The Third Reich is Listening is a gripping blend of modern history and science, and describes the successes and failures of Germany's codebreaking and signals intelligence operations from 1935 to 1945. The first mainstream book to take an in-depth look at German cryptanalysis in World War II, it tells how the Third Reich broke the ciphers of Allied and neutral countries, including Great Britain, France, Russia and Switzerland. This book offers a dramatic new perspective on one of the biggest stories of World War II, using declassified archive material and colourful personal accounts from the Germans at the heart of the story, including a former astronomer who worked out the British order of battle in 1940, a U-Boat commander on the front line of the Battle of the Atlantic, and the German cryptanalyst who broke into and read crucial codes of the British Royal Navy.

In this pathbreaking book, Amy Zegart provides the first scholarly examination of the intelligence failures that preceded September 11. Until now, those failures have been attributed largely to individual mistakes. But Zegart shows how and why the intelligence system itself left us vulnerable.

Zegart argues that after the Cold War ended, the CIA and FBI failed to adapt to the rise of terrorism. She makes the case by conducting painstaking analysis of more than three hundred intelligence reform recommendations and tracing the history of CIA and FBI counterterrorism efforts from 1991 to 2001, drawing extensively from declassified government documents and interviews with more than seventy high-ranking government officials. She finds that political leaders were well aware of the emerging terrorist danger and the urgent need for intelligence reform, but failed to achieve the changes they sought. The same forces that have stymied intelligence reform for decades are to blame: resistance inside U.S. intelligence agencies, the rational interests of politicians and career bureaucrats, and core aspects of our democracy such as the fragmented structure of the federal government. Ultimately failures of adaptation led to failures of performance. Zegart reveals how longstanding organizational weaknesses left unaddressed during the 1990s prevented the CIA and FBI from capitalizing on twenty-three opportunities to disrupt the September 11 plot.

"Spying Blind" is a sobering account of why two of America's most important intelligence agencies failed to adjust to new threats after the Cold War, and why they are unlikely to adapt in the future.

For most Arab regimes, intelligence, security apparatus and the secret services, are central to their domestic politics. Yet despite this, very little scholarly attention has been paid to the relationship between intelligence and politics in any Arab state. This book examines how security apparatus and intelligence influenced the domestic politics of Tunisia, from the implementation of French Protectorate in 1881 to the aftermath of the independence up to 1965. Based on unprecedented access to the sources of the Ministry of Interior and the First Ministry during Bourguiba's regime, as well as the national, diplomatic and military archives of France, Italy and the United Kingdom, the book is the first to trace the evolution of the Tunisian security community. Omar Safi argues that from an apparatus designed to maintain colonial control, intelligence became an instrument to drive the political agendas of the ruling elite. The book sheds new light on the influence of intelligence, presenting it as the fundamental, and generally ignored, 'missing dimension' of North African domestic politics.

Drawing on extensive interviews and archival research, this biography uncovers the motivations and ideals that informed Smiley's commitment to covert action and intelligence during the Second World War and early part of the Cold War, often among tribally based societies. With particular reference to operations in Albania, Oman and Yemen, it addresses the wider issues of accountability and control of clandestine operations.

Learning from history helps states to create foreign and security policy that builds upon successes and avoids past mistakes. Louise Kettle's insightful analysis - drawing on a wealth of previously unseen documents, sourced by Freedom of Information requests, together with interviews with government and intelligence agency officials - questions whether the British government actually learns from history. This is achieved through an extended commentary on military interventions in the Middle East since the 1950s, including a behind-the-scenes glimpse into Whitehall decision-making and a critical examination of the 2016 Iraq Inquiry report.

Repeated intelligence failures in Iraq, Libya and across the Middle East and North Africa have left many critics searching for a smoking gun. Amidst questions of who misread - or manipulated - the intel, a fundamental truth goes unaddressed: western intelligence is not designed to understand the world. In fact, it cannot. In The Covert Colour Line, Oliver Kearns shows how the catastrophic mistakes made by British and US intelligence services since 9/11 are underpinned by orientalist worldviews and racist assumptions forged in the crucible of Cold War-era colonial retreat. Understanding this historical context is vital to explaining why anglophone state intelligence is unable to grasp the motives and international solidarities of 'adversaries'. Offering a new way of seeing how intelligence contributes to world inequalities, and drawing on a wealth of recently declassified materials, Kearns argues that intelligence agencies’ imagination of 'non-Western' states and geopolitics fundamentally shaped British intelligence assessments which would underpin the 2003 invasion of Iraq and subsequent interventions.

When British troops first deployed to Northern Ireland in 1969 to keep apart rioting factions of loyalists and nationalists, they could not have known that they were being drawn into the longest campaign in the British Army's history, a battle against the threat of a new rising force - the Provisional Irish Republican Army.

While patrols, vehicle bombs and incendiary speeches are the defining memories of the Troubles, the real war was fought out of sight and out of mind. For thirty years, Britain's Special Forces waged a ferocious, secretive struggle against a ruthless and implacable enemy.

Harry McCallion's deep experience across the theatre of Northern Ireland offers a unique insight into nearly every major military action and operation in the Province. Having served seven tours with the Parachute Regiment, undergone selection for 14 Intelligence Company, completed six years with the SAS - including two tours with their anti-terrorism team - and received two commendations for bravery during service with the Royal Ulster Constabulary, there are few more qualified to tell this astonishing story.

This book is his blistering account of the history of Britain's war against the IRA between 1970 and 1998. From new insights into high-profile killings and riveting accounts of enemy contact, to revelations about clandestine missions and the strategies used in combating a merciless enemy, Undercover War is the definitive inside story of the battle against the IRA, one of the most dangerous and effective terrorist organisations in recent history.

Britain's war in the shadows of male spies and subterfuge in the heart of occupied France is a story well known, but what of the women who also risked their lives for Britain and the liberation of France? In 1942 a desperate need for new recruits, saw SOE turn to a previously overlooked group - women. These extraordinary women came from different backgrounds, but were joined in their idealistic love of France and a desire to play a part in its liberation. They formed SOE's F Section. From the famous White Mouse, Nancy Wake, to the courageous, Noor Inayat Khan, they all risked their lives for King, Country and the Resistance. Many of them died bravely and painfully, and often those who survived, like Eileen Nearne, never told their stories, yet their secret missions of intelligence-gathering and sabotage undoubtedly helped the Resistance to drive out their occupiers and free France. Here, for the first time is the extraordinary account of all forty SOE F women agents. It is a story that deserves to be read by everyone. 'They were the war's bravest women, devoted to defeating the Nazis yet reluctant ever to reveal their heroic pasts. Now a new book tells their intrepid tales.' Daily Express Squadron Leader BERYL E. ESCOTT served in the RAF and is one of the foremost experts on the women of SOE.

The intelligence community's flawed assessment of Iraq's weapons systems -- and the Bush administration's decision to go to war in part based on those assessments -- illustrates the political and policy challenges of combating the proliferation of weapons of mass destruction. In this comprehensive assessment, defense policy specialists Jason Ellis and Geoffrey Kiefer find disturbing trends in both the collection and analysis of intelligence and in its use in the development and implementation of security policy.

Analyzing a broad range of recent case studies -- Pakistan's development of nuclear weapons, North Korea's defiance of U.N. watchdogs, Russia's transfer of nuclear and missile technology to Iran and China's to Pakistan, the Soviet biological warfare program, weapons inspections in Iraq, and others -- the authors find that intelligence collection and analysis relating to WMD proliferation are becoming more difficult, that policy toward rogue states and regional allies requires difficult tradeoffs, and that using military action to fight nuclear proliferation presents intractable operational challenges.

Ellis and Kiefer reveal that decisions to use -- or overlook -- intelligence are often made for starkly political reasons. They document the Bush administration's policy shift from nonproliferation, which emphasizes diplomatic tools such as sanctions and demarches, to counterproliferation, which at times employs interventionist and preemptive actions. They conclude with cogent recommendations for intelligence services and policy makers.

A new, fully uncensored edition of the definitive insider's account of the War on Terror 'A former FBI agent's memoir on the War on Terror is declassified after 9 years' Time 'One of the most valuable and detailed accounts of its subject to appear in the past decade' Economist The ultimate insider's account of the battle against terrorism, Ali Soufan's revelatory account of his history-making decade as the FBI's lead investigator into al-Qaeda shaped our understanding of counter-terror operations - and led to hard questions being asked of American and British leaders. When The Black Banners was first published in 2011, significant portions of the text were redacted. After a CIA review those restrictions have been lifted, and the result is this explosive new edition, The Black Banners (Declassified). Alongside a new foreword by Soufan, the declassified documents uncover shocking details on the use of torture on terror suspects, how these 'enhanced interrogation techniques' failed to secure reliable intelligence, and in fact actively derailed the fight against al-Qaeda. By contrast we see Soufan at work using empathy and intelligent questioning - not force or violence - to extract some of the most important confessions in the war. Taking us from the interrogation rooms where Soufan would share food and films with the suspects so he could bond with them, to the hideouts of bin Laden, Ali Soufan reveals with intimate, first-hand knowledge the unbelievable truth about America's security agencies, 9/11, and the global 'War on Terror'.

This powerful study makes a compelling case about the key U.S. role in state terrorism in Latin America during the Cold War. Long hidden from public view, Operation Condor was a military network created in the 1970s to eliminate political opponents of Latin American regimes. Its key members were the anticommunist dictatorships of Chile, Argentina, Uruguay, Bolivia, Paraguay, and Brazil, later joined by Peru and Ecuador, with covert support from the U.S. government. Drawing on a wealth of testimonies, declassified files, and Latin American primary sources, J. Patrice McSherry examines Operation Condor from numerous vantage points: its secret structures, intelligence networks, covert operations against dissidents, political assassinations worldwide, commanders and operatives, links to the Pentagon and the CIA, and extension to Central America in the 1980s. The author convincingly shows how, using extralegal and terrorist methods, Operation Condor hunted down, seized, and executed political opponents across borders. McSherry argues that Condor functioned within, or parallel to, the structures of the larger inter-American military system led by the United States, and that declassified U.S. documents make clear that U.S. security officers saw Condor as a legitimate and useful 'counterterror' organization. Revealing new details of Condor operations and fresh evidence of links to the U.S. security establishment, this controversial work offers an original analysis of the use of secret, parallel armies in Western counterinsurgency strategies. It will be a clarion call to all readers to consider the long-term consequences of clandestine operations in the name of 'democracy.'

Signals Intelligence, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War. In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty's famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers. "SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." - The St Ermin's Hotel Intelligence Book of the Year Award 2014

Tony Brooks was unique. He was barely out of school when recruited in 1941 by the Special Operations Executive (SOE), the wartime secret service established by Churchill to 'set Europe ablaze'. After extensive training he was parachuted into France in July 1942 - being among the first (and youngest) British agents sent to support the nascent French Resistance. Brook's success was primarily due to his exceptional qualities as a secret agent, although he was aided by large and frequent slices of luck. Among much else, he survived brushes with a British traitor and a notorious double agent; the Gestapo's capture of his wireless operator and subsequent attempts to trap Brooks; brief incarceration in a Spanish concentration camp; injuries resulting from a parachute jump into France; and even capture and interrogation by the Gestapo - although his cover story held and he was released. In an age when we so often take our heroes from the worlds of sport, film, television, music, fashion, or just 'celebrity', it is perhaps salutary to be reminded of a young man who ended the war in command of a disparate force of some 10,000 armed resistance fighters, and decorated with two of this country's highest awards for gallantry, the DSO and MC. At the time, he was just twenty-three years old. This remarkable, detailed and intimate account of a clandestine agent's dangerous wartime career combines the historian's expert eye with the narrative colour of remembered events. As a study in courage, it has few, if any, equals.

State sponsorship of terrorism is a complex and important topic in today's international affairs - and especially pertinent in the regional politics of the Middle East and South Asia, where Pakistan has long been a flashpoint of Islamist politics and terrorism. In Islamism and Intelligence in South Asia, Prem Mahadevan demonstrates how over several decades, radical Islamists, sometimes with the tacit support of parts of the military establishment, have weakened democratic governance in Pakistan and acquired progressively larger influence over policy-making. Mahadevan traces this history back to the anti-colonial Deobandi movement, which was born out of the post-partition political atmosphere and a rediscovery of the thinking of Ibn Taymiyyah, and partially ennobled the idea of `jihad' in South Asia as a righteous war against foreign oppression. Using Pakistani media and academic sources for the bulk of its raw data, and reinforcing this with scholarly analysis from Western commentators, the book tracks Pakistan's trajectory towards a `soft' Islamic revolution. Envisioned by the country's intelligence community as a solution to chronic governance failures, these narratives called for a re-orientation away from South Asia and towards the Middle East. In the process, Pakistan has become a sanctuary for Arab jihadist groups, such as Al-Qaeda, who had no previous ethnic or linguistic connection with South Asia. Most alarmingly, official discourse on terrorism has been partly silenced by the military-intelligence complex. The result is a slow drift towards extremism and possible legitimation of internationally proscribed terrorist organizations in Pakistan's electoral politics.

All democracies have had to contend with the challenge of tolerating hidden spy services within otherwise relatively transparent governments. Democracies pride themselves on privacy and liberty, but intelligence organizations have secret budgets, gather information surreptitiously around the world, and plan covert action against foreign regimes. Sometimes, they have even targeted the very citizens they were established to protect, as with the COINTELPRO operations in the 1960s and 1970s, carried out by the Federal Bureau of Investigation (FBI) against civil rights and antiwar activists. In this sense, democracy and intelligence have always been a poor match. Yet Americans live in an uncertain and threatening world filled with nuclear warheads, chemical and biological weapons, and terrorists intent on destruction. Without an intelligence apparatus scanning the globe to alert the United States to these threats, the planet would be an even more perilous place. In Spy Watching, Loch K. Johnson explores the United States' travails in its efforts to maintain effective accountability over its spy services. Johnson explores the work of the famous Church Committee, a Senate panel that investigated America's espionage organizations in 1975 and established new protocol for supervising the Central Intelligence Agency (CIA) and the nation's other sixteen secret services. Johnson explores why partisanship has crept into once-neutral intelligence operations, the effect of the 9/11 attacks on the expansion of spying, and the controversies related to CIA rendition and torture programs. He also discusses both the Edward Snowden case and the ongoing investigations into the Russian hack of the 2016 US election. Above all, Spy Watching seeks to find a sensible balance between the twin imperatives in a democracy of liberty and security. Johnson draws on scores of interviews with Directors of Central Intelligence and others in America's secret agencies, making this a uniquely authoritative account.

In 2013, Edward Snowden revealed that the NSA and its partners had been engaging in warrantless mass surveillance, using the internet and cellphone data, and driven by fear of terrorism under the sign of security . In this compelling account, surveillance expert David Lyon guides the reader through Snowden s ongoing disclosures: the technological shifts involved, the steady rise of invisible monitoring of innocent citizens, the collusion of government agencies and for-profit companies and the implications for how we conceive of privacy in a democratic society infused by the lure of big data. Lyon discusses the distinct global reactions to Snowden and shows why some basic issues must be faced: how we frame surveillance, and the place of the human in a digital world. Surveillance after Snowden is crucial reading for anyone interested in politics, technology and society.

Many Americans know something about the Navajo code talkers in World War II-but little else about the military service of Native Americans, who have served in our armed forces since the American Revolution, and still serve in larger numbers than any other ethnic group. But, as we learn in this splendid work of historical restitution, code talking originated in World War I among Native soldiers whose extraordinary service resulted, at long last, in U.S. citizenship for all Native Americans. The first full account of these forgotten soldiers in our nation's military history, The First Code Talkers covers all known Native American code talkers of World War I-members of the Choctaw, Oklahoma Cherokee, Comanche, Osage, and Sioux nations, as well as the Eastern Band of Cherokee and Ho-Chunk, whose veterans have yet to receive congressional recognition. William C. Meadows, the foremost expert on the subject, describes how Native languages, which were essentially unknown outside tribal contexts and thus could be as effective as formal encrypted codes, came to be used for wartime communication. While more than thirty tribal groups were eventually involved in World Wars I and II, this volume focuses on Native Americans in the American Expeditionary Forces during the First World War. Drawing on nearly thirty years of research-in U.S. military and Native American archives, surviving accounts from code talkers and their commanding officers, family records, newspaper accounts, and fieldwork in descendant communities-the author explores the origins, use, and legacy of the code talkers. In the process, he highlights such noted decorated veterans as Otis Leader, Joseph Oklahombi, and Calvin Atchavit and scrutinizes numerous misconceptions and popular myths about code talking and the secrecy surrounding the practice. With appendixes that include a timeline of pertinent events, biographies of known code talkers, and related World War I data, this book is the first comprehensive work ever published on Native American code talkers in the Great War and their critical place in American military history.

The British government's top secret Code & Cypher School at Bletchley Park, otherwise known as Station X, was the unlikely setting for one of the most vital undercover operations of the Second World War. It was at Bletchley in present-day Milton Keynes that teams of code breakers succeeded in cracking Germany's supposedly unbreakable Enigma codes, thereby shortening the war by at least two years.

Marion Hill has used the transcripts of some 200 interviews and memoirs from among the thousands of people who worked at Station X to give a remarkable insight into the daily lives of the civilian and service personnel who contributed to the breaking of the Enigma and other Axis codes. She explores their recruitment and training, their first impressions on arrival at Bletchley Park ('BP'), their working conditions, (including the in house food and entertainment), and their time off in billets and beyond. These BP workers, from boffins and debs to ex-bank clerks and engineers, were united in the need to 'keep mum' - even with their family and close friends. However, the stressful burden of secrecy created divisions within the organisation, and illnesses; and many felt disappointed at the lack of acknowledgement for a vital job about which they were forbidden to speak until many years later.

A selection of archive photographs and illustrations accompanies the text, drawn from the Bletchley Park Trust Archive and from the personal albums of those stationed at Bletchley.

An attack by a British destroyer on a German U-boat in the Eastern Mediterranean in October 1942 altered the course of the entire war. The capture of secret coding material from U-559, at the cost of two of HMS Petard's crew, enabled Bletchley Park's codebreakers to successfully crack the U-boat cypher. It was the crucial factor in defeating Hitler's Atlantic U-boat wolf packs before they succeeded in starving Britain into defeat in the winter of 1942-1943. Here is the true story of how HMS Petard attacked and captured U-559 in the darkness of a Mediterranean night. It describes how members of her crew swam across to the slowly sinking U-boat and captured vital German Enigma codebooks. But the damage sustained by U-559 in the earlier attack proved fatal and without warning she sank before Petard could take her in tow. Two of the destroyer's crew were trapped in the conning tower and went to the bottom with her. Both men were later recommended for posthumous awards of the Victoria Cross but the Admiralty, concerned this might draw unwanted attention from German Intelligence, instead ordered posthumous awards of the George Cross, the highest civilian award for bravery.
