An extremely overrated president. A criminal. The Kennedy money came from stealing and murdering. He was assassinated by the only sane person left in the country at the time. After that, the whole country went insane, therefore inflating JFK's insane popularity. If Oswald didn't kill him, you would learn about a criminal, terrible president, and whore user person thingy in school.
Thanks to my grandpa, G. Warren Nutter (assistant secretary of defense of foreign affairs during the latter end of the Vietnam war), JFK's stupid war was won, but the stupid population wanted to end it because they actually thought we were loosing. HA! dumbasses
