Maybe the Guy is an Anti-War Protester who enlisted to set this up?
A third possibility is not out of the question. Perhaps he is an anti-war protester who enlisted to set up this opportunity to protest the war. After all, it is very effective in gathering the media to listen to his protest message.
I find it hard to believe he is so stupid as to not understand he would be called upon to serve in Iraq or Afghanistan since he enlisted after the war kicked off.
