THE CRISIS
USSR/CUBA

SUMMARY CONTENTS

I. Based on the latest low-level reconnaissance mission, three of the four MRBM sites at San Cristobal and the two sites at Sagua La Grande appear to be fully operational. No further sites or missiles have been identified.

The mobilization of Cuban military forces continues at a high rate. However, they remain under orders not to take any hostile action unless attacked.

Steps toward establishing an integrated air defense system are under way. On the diplomatic front, Cuban representatives are trying to plant the idea that Havana would be receptive to UN mediation. They indicate, however, that a prerequisite must be “proof” that the US does not intend to attack Cuba.

II. Despite Khrushchev’s declaration to U Thant that Soviet ships would temporarily avoid the quarantine area, we have no information as yet that the six Soviet and three satellite ships en route have changed course. A Swedish vessel, believed to be under charter to the USSR, refused to stop yesterday when intercepted by a US destroyer and was allowed to continue to Havana.

III. No significant redeployment of Soviet ground, air or naval forces have been noted. However, there are continuing indications of increased readiness among some units. Three F-class submarines have been identified on the surface inside or near the quarantine line.

IV. There has been no distinct shift in the pattern of reaction. In Western Europe, further support for the US has come from several quarters and unfavorable reactions are decidedly in the minority.

Official London seems intent on checking premature optimism which is showing up in widely scattered parts of the world, particularly among the neutrals. French support for the US is hardening.

There are reports that anti-US demonstrations have broken out in several Latin American capitals, including Buenos Aires, Caracas, and La Paz.
