I believe but can't prove

Oswald was a loner and a nut. But I don't think a lone nut. I think he did have big ambitions but was either too uneducated or too much of an ahole to achieve those ambitions in a normal perspective. Were his ambitions to be satisfied with the killing of JFK? I don't know. I have done a lot of reading but can't figure out his motivation behind the assassination.
