In practice, yes. Though he claimed repeatedly that Marxism was the only feasible social system. But he was a disturbed man. Delusions of grandeur and persecution. He expected to be treated as a superior when he was in the Marine Corps, he expected to be treated as a hero and a celebrity when he defected to the Soviet Union (he thought that his time as a radar operator made him a valuable intelligence resource, the KGB thought that he was an attention seeker and that any information that he had, they already knew), when he was put to work (Marxist/Leninist/Stalinist-style) in a radio/TV factory working a drill-press, he (again) felt that he was being unrecognized and underappreciated. So, he returned to the US and actually expected that he would be greeted by throngs of supporters and reporters all dying to hear his story. He was a 20 something year old with mental issues who thought that he deserved attention and adulation even though he never was accomplished or exceptional at anything (sound familiar?). IMO, his reason for shooting Kennedy (especially when he asked for John Abt, chief counsel to the US Communist Party to defend him when he was in DPD custody) was that he felt that he could commit a high-profile crime, get a huge show trial, and (finally) be not only the center of attention, but get everyone to pay attention to his views. Lee Oswalt was (IMO) nearly 50 years ahead of his time when it came to deranged shooters who wanted fame via the path of violent infamy.
