I think he Oswald felt he was a failure and for the United States and for President Kennedy and all of us. He knew he was a failure at everything he tried frustrated with a very sad life but he was a Marxist.
The only time I commit to conspiracy theories is when something way retarded happens. Like Lee Harvey Oswald acting alone.
I really hate sitcoms on television with canned laughter and stuff. What really makes me laugh is the real-life stuff. I've got a dry sense of humor.
