Over the years, the United States has been concerned about threats to Latin American and Caribbean nations from various terrorist or insurgent groups that have attempted to influence or overthrow elected governments. Although Latin America has not been the focal point in the war on terrorism, countries in the region have struggled with domestic terrorism for decades and international terrorist groups have at times used the region as a battleground to advance their causes. This book examines Latin America as a national security threat with a focus on Iran's increasing activities with Venezuela; drug-trafficking related violence in Mexico and Columbia; and Cuba's lack of cooperation in antiterrorism efforts.
