WASHINGTON: WikiLeaks has released a CIA memo analysing the risks of terrorists operating from the United States.

The CIA paper - titled What if Foreigners See the United States as an ''Exporter of Terrorism''? - examines the implications of extremists recruiting US nationals and using the US as a base for attacks abroad.

The US has long been an exporter of terrorism, according to the analysis.

If that became a widely held perception it could damage relations with foreign allies and lessen their willingness to co-operate in ''extrajudicial'' activities, such as the abduction and interrogation of terrorism suspects, known as rendition.

The three-page secret paper was produced in February by the CIA's Red Cell, which was set up after the attacks of September 11, 2001 by the then-CIA director, George Tenet, to provide ''out-of-the-box'' analyses on ''a full range of analytic issues''.
