Cuba President Raul Castro Honors Ernesto Guevara in Santa Clara

"useful idiots"

I agree with the second half of this, but must argue against the first half!

Che was willing to nuke the US. Wikipedia:

Guevara, who was practically the architect of the Soviet–Cuban relationship, then played a key role in bringing to Cuba the Soviet nuclear-armed ballistic missiles that precipitated the Cuban Missile Crisis in October 1962 and brought the world to the brink of nuclear war. A few weeks after the crisis, during an interview with the British communist newspaper the Daily Worker, Guevara was still fuming over the perceived Soviet betrayal and told correspondent Sam Russell that, if the missiles had been under Cuban control, they would have fired them off. While expounding on the incident later, Guevara reiterated that the cause of socialist liberation against global "imperialist aggression" would ultimately have been worth the possibility of "millions of atomic war victims". The missile crisis further convinced Guevara that the world's two superpowers (the United States and the Soviet Union) used Cuba as a pawn in their own global strategies. Afterward, he denounced the Soviets almost as frequently as he denounced the Americans.
