Well his indirect slam of the GOP by equating them with the Democrats surely raises questions about his agenda. The Republican party is the biggest supporter the troops have. There are lots of ways to support the war effort besideds signing up. What this guy is doing is subtly using the old 'chickenhawk' slur. If he really believes this I have to wonder if he really knows what he's talking about or if he's really who he says he is.
Irreguardless of who he is or his motives...some of his points have merit. Sure some of his points sound sketch, but some of the others I have personally heard from many a man (and woman) in the military.
