Foreign Relations of the United States, 1961–1963, Volume XI, Cuban Missile Crisis and Aftermath

148. Memorandum From President Kennedy to Secretary of Defense McNamara⁰

Washington, November 5, 1962.

We must operate on the presumption that the Russians may try again. This time they may prepare themselves for action on the sea in the Cuban area. Does Admiral Anderson think they could build up a secret subterranean base which will put them on a near parity with us if we should once again blockade. If he thinks there is substantial danger of this what suggestions would he now make?

John F. Kennedy¹
