Alternate Title: NSDD 138: Combating Terrorism
From the Document: "NSDD [National Security Decision Directive] 138 was issued in 1984 by the Reagan administration. Much of this NSDD is classified, but, reportedly permitted the CIA and the FBI to form covert operations teams and to use military special operations forces to conduct guerrilla-style war against guerrillas, pre-emptive operations, retaliation, expanded intelligence collection, and when necessary, killing of guerrillas in 'pre-emptive' self-defense. States that sponsored terrorists (Iran, Libya, Syria, Cuba, North Korea) could be targeted for operations."
