In March 1979, "CIA sent several covert action options relating to Afghanistan to the SCC [Special Coordination Committee]" of the United States National Security Council. At a March 30 meeting, U.S. Department of Defense representative Walter B. Slocombe "asked if there was value in keeping the Afghan insurgency going, 'sucking the Soviets into a Vietnamese quagmire?'" When asked to clarify this remark, Slocombe explained: "Well, the whole idea was that if the Soviets decided to strike at this tar baby we had every interest in making sure that they got stuck." Yet an April 5 memo from National Intelligence Officer Arnold Horelick warned: "Covert action would raise the costs to the Soviets and inflame Moslem opinion against them in many countries. The risk was that a substantial U.S. covert aid program could raise the stakes and induce the Soviets to intervene more directly and vigorously than otherwise intended."
