I've yet to meet one that can outsmart Bullitt

William Christian Bullitt Jr. was an American diplomat, journalist, and novelist. He is known for his special mission to negotiate with Lenin on behalf of the Paris Peace Conference, often recalled as a missed opportunity to normalize relations with the Bolsheviks. He was also the first US ambassador to the Soviet Union and the US ambassador to France during World War II. In his youth, he was considered a radical, but he later became an outspoken anticommunist.
