U.S. attention to terrorism in Latin America intensified in the aftermath of the September 2001 terrorist attacks on New York and Washington, with an increase in bilateral and regional cooperation. In its 2010 Country Reports on Terrorism (issued in August 2011), the State Department maintained that terrorism in the region was primarily perpetrated by terrorist organizations in Colombia and by the remnants of radical leftist Andean groups. Overall, however, the report maintained that the threat of a transnational terrorist attack remained low for most countries in the hemisphere. With regard to concerns about drug trafficking-related violence in Mexico, the State Department terrorism report asserted that "there was no evidence of ties between Mexican criminal organizations and terrorist groups, nor that the criminal organizations had aims of political or territorial control, aside from seeking to protect and expand the impunity with which they conduct their criminal activity." Cuba has remained on the State Department's list of state sponsors of terrorism since 1982 pursuant to Section 6(j) of the Export Administration Act, which triggers a number of economic sanctions. Both Cuba and Venezuela are on the State Department's annual list of countries determined to be not cooperating fully with U.S. antiterrorism efforts pursuant to Section 40A of the Arms Export Control Act. U.S. officials have expressed concerns over the past several years about Venezuela's lack of cooperation on antiterrorism efforts, its relations with Iran, and potential support for Colombian terrorist groups.
