By the 18th of October, the President needed to meet with a Soviet representative. Although it was not time for the Soviets to know the Americans were "on to them," the President discussed Soviet intentions in Cuba. Advancing the "defensive weapons only" argument, Soviet Foreign Minister Andrei Gromyko denied America had cause for concern.

At 11 a.m., JFK meet with Ex Comm. Members discussed various options, including a naval quarantine [euphemism for blockade] of Cuba. At the end of the meeting, the President recorded a summary of the day’s discussions. Let’s listen in. (Scroll down about 10% to October 18, 1962.)

The next day, General LeMay urged the President to take out the missiles by air strike. Concerned about that approach, the President concedes:

The problem for the President, of course, was not just offensive nuclear missiles located so close to America. If he initiated military action against Cuba, what would the Soviets do in Berlin? The President’s overriding concern was: As Cuba goes, so goes Berlin. European allies cared a lot more about Berlin than they cared about a small island thousands of miles away. JFK said he didn’t want U.S. Allies to view his country as "trigger-happy Americans." (Follow the link to hear the Ex Comm discussion.)

Meanwhile, more U-2 missions disproved Gromyko’s assurances. Construction at the missile launch sites (including those for the longer-range SS-5) was accelerating.
