Llewellyn Thompson

Background and position

Thompson was a career diplomat who had recently completed a posting as ambassador to the Soviet Union. He became ambassador at large in October 1962. Experience of Moscow gave him a different perspective from advisers whose work centred on American military capabilities or domestic political pressures.

Role in October 1962

Thompson advocated communicating with Khrushchev and supported a blockade before military action. He also stressed the need to allow time for Soviet instructions to reach ship captains. His contribution illustrates how knowledge of an opponent’s government could affect the timing and presentation of American decisions.

He treated communication as a process that could fail through delay as well as disagreement. A decision in Moscow was not instantly known to a Soviet ship’s captain. Allowing time for instructions to arrive could prevent an encounter at sea from defeating negotiations between the leaders.

Advice that changed with the situation

Thompson’s 20 October position was not a simple rejection of force. He supported a blockade first but contemplated an air strike after warning Soviet personnel. The record complicates the idea that the advisers belonged to two unchanging camps throughout the crisis.

At the 27 October afternoon meeting, he cautioned against drawing firm conclusions from a report that a reconnaissance aircraft had been fired on. A local military action did not automatically disclose the Soviet leadership’s intentions. That distinction was especially valuable while communications and intelligence were incomplete.

Why their role matters

His contribution was to make the Soviet side’s choices part of the discussion. Understanding how Khrushchev could accept a settlement without presenting it as humiliation was a practical diplomatic problem, not an expression of sympathy for Soviet policy.
