When I was in the military it was beaten into me that you never criticized the political leadership. Once you put on the uniform you were there to obey all legal orders. Dissenters had two honorable choices: drive a POV up the chain of command and/or leave the military and then have at it. This is because civilian control of the military is the foundation of western democracy. Are there stupid politicians? Yes. The military chain of command is IMO little better. But let's remember the oath we took and the principles that stand behind it.
