Interesting that you have President Eisenhower being assassinated in 1963. Oswald had mentioned to a fellow marine in the mid-50's that he would like to kill Eisenhower, who was president at the time. Oswald was a marxist and hated the United States' form of Government. In this timeline, it is very possible that an assassination could occur again, as in real time. ...Thank you.
