My understanding of a chickenhawk in this context is one who promotes war without having ever participated in such conflict.

If that's correct, Obama would've fit that definition in textbook perfection. He promised to pull us out of Iraq and Afghanistan. We're still there and virtually every other sh!t hole on the planet. In fact, he's done it in an even more insidious way. Relying highly on uav strikes where there's no dead soldiers for the media to capitalize on. Wouldn't that be pure chickenhawk?
