I imagine that as a former soldier he feels a lot of camaraderie with the troops so I will give him the benefit of the doubt. If he did it without announcing it and with no news coverage I would give him even more credit
but is he going to go for a stroll in an Iraqi market without helicpoters, body Armor and a platoon of Marines this time?
First, actually he was a sailor, NOT a soldier.
Second, given the trouble he is having raising money in the United States, he may be going abroad to try to raise money elsewhere.
Third, he may find Iraq to be friendlier territority than Arizona. There he only has to recokon with terrorists while in Arizona the average citizen hates him.
