Lee Harvey Oswald wasn't a crazed loner -- he didn't shoot JFK because he thought the White House was beaming mind control waves into his brain. He had an actual beef with the American government, and by that we mean he was kind of a communist sympathizer. So much so that, four years before he climbed to the sixth floor of a book depository and became one of the most hated men in American history, he flipped America the middle finger by defecting to the Soviet Union. And since he was just a random, whiny douche at that point, America didn't put up a big fight to keep him. Would you?
Unfortunately for the whole world, life in Soviet Russia wasn't as exciting as Cold War propaganda posters let on. By 1959, the USSR was more like the bleak, gray, impoverished, always-snowing suicide trap you see in photos like these:
Those aren't hats.
Oswald had hoped to study at Moscow University, but the Soviets had a job opening for a lathe operator in Minsk, and apparently, in Soviet Russia, the job chose you. (Sorry.) The idealistic Oswald must have been pretty disappointed by what he saw. So did he change his mind, having a revelation that maybe the American way was better? Eh, not exactly.
