Kennedy Assassination Conspiracy Theories

I think Oswald was part of the K.G.B., because it says that he lived in Russia for a few years before he returned to the United States. Maybe, because of the tension between the Americans and the Soviets, he came back trying to cause a war between the two countries. The Soviet Union might have agreed to remove the missiles in Cube because the U.S. said they would remove their missiles from Turkey, and they did, but what the Soviets really wanted was to actually go to war with America and destroy most of the important cities, and then after that the Soviet Union could be number one in the world, with military power and economy. And, when Oswald was assassinated, people started saying that if the assassin hadn't killed him, Oswald would've said something and confess why he assassinated JFK. But maybe, that was the reason the night club owner killed Oswald. Everyone knew he was friends with the police, but who knew if he was behind the crime and just wanted to make sure Oswald wouldn't confess anything, because he didn't want to get in trouble, even though he did after he assassinated Oswald.
