I agree. The political power plays in many of the tecnothrillers are my favorite part. It's fun to watch what might happen in the highest offices of political and military power in a crisis situation.
Sadly, Clancy seems to be losing his touch, if his last three books are any indication.
Teeth of the Tiger had too many loose ends. It wasn't bad, but I didn't like the ending at all.
Bear and the Dragon was good. Executive Orders was probably my favorite.
