34. Memorandum From William Odom of the National Security Council Staff to the President’s Assistant for National Security Affairs (Brzezinski)1

SUBJECT

  • Crisis Potential: Soviet Units in Cuba

[less than 1 line not declassified] there is an [less than 1 line not declassified] report of Soviet tank troops in Cuba.2 I have queried the intelligence community on this to learn that the evidence is far from conclusive. The [less than 1 line not declassified] is compatible with as benign an interpretation as Soviet military advisers going out for their annual summer military reserve training in groups of a dozen or so. The [less than 1 line not declassified] could be as benign as “maneuvers” on a tank driving exercise course. In a word, the situation is very unclear. Arnold Horelick reports that an intensified effort to clarify the situation is under way.

He was worried that we might overreact. I am giving you this memorandum to provide a better sense of limits and validity of [less than 1 line not declassified]
