Yes because in one case your actions are in service of your country and in the other you will be declared a traitor and executed as such.
Edit: Did you read the "JFK decided to withdraw" link? He allegedly decided to withdraw 1000 of 17,000 Americans in Vietnam. This one step forward two steps back military strategy is par for the course for the duration of the Vietnam War. Doesn't substantiate at all why CIA would be so upset about it as to assassinate POTUS. Per your own link, it was a minor enough move that they didn't feel the need even to consult or notify South Vietnamese President Diem.
