Thrillers that make you think?

False Refuge by Steve Anderson. From my review:

This is a thought-provoking book, dealing as it does with one man's decision to go AWOL rather than be sent to war. The question of whether Alex has deserted his mates or exercised his right to refuse service in an illegal war is not a simple one. Anderson, however, manages to have his characters explore that question without bogging down the story. In the action scenes, this book reminded me of an Andy McNab thriller.
