The Munich Security Conference, founded as "Wehrkundetagung" in 1963, has evolved into the leading independent forum for security policy. Traditionally seen as a kind of transatlantic family meeting for debating NATO strategy during the Cold War, the conference has increasingly broadened its agenda and today attracts participants from across the globe. Each year, dozens of heads of state and government, ministers, and experts from different fields of security policy gather in Munich for an open exchange of ideas and policies on the most pressing international security issues - ranging from regional conflicts, international peace operations and nuclear disarmament to cyber security and environmental challenges. On the occasion of the conference's 50th anniversary in 2014, a number of prominent participants, including former and current foreign and defense ministers, reflect on the conference's history and significance, some of the major issues debated, and on key security challenges facing the international community.
