“JAN 25, 1961: President [John F.] Kennedy meets with the Joint Chiefs of Staff at the White House. According to a memorandum on the meeting, Gen. [Lyman] Lemnitzer [Chairman of the Joint Chiefs of Staff] tells the President that in light of the ‘shipment of heavy new military equipment from Czechoslovakia-30,000 tons or more-clandestine forces are not strong enough. [The U.S.] must increase the size of this force and this creates very difficult problems. What is required is a basic expansion of plans.’”
