Ho Chi Minh wasn't the only bearded revolutionary out there. Che Guevara can be counted alongside Minh and the other revolutionary figures that came to define the post-World War II world.

Guevara gained a name for himself by fighting alongside the most famous revolutionary beard of all time: that of Fidel Castro. He and Castro were central figures in the Cuban Revolution that took place between 1953 and 1959.

But Guevara didn't stop there. He made it his personal mission to spread the word of revolutionary socialism and the importance of a well-maintained beard in the revolutionary battlefield. Importantly, though, he saw himself as a spokesperson of what he argued were the oppressed classes.

This is where the speech that he gave at the United Nations in 1964 comes into play. During the speech, Guevara spoke about the Vietnam War. He actually spoke about a lot of things, but he mostly pinned most of the world's problems—including the war in Vietnam—on two major sources: imperialism and the United States.

Five years later, Richard Nixon would address the "great silent majority" in America. In that speech, he mostly blamed Vietnam for preventing peace. In 1964, Che Guevara blamed the United States for preventing peace.

Sure, it may sound like the old schoolyard tactic "I know you are (a violent aggressor that has ruined world politics and the chances for peaceful coexistence), but what am I?" Actually, now that we mention it, that saying could characterize the entire Cold War.
