re: "stupid, afraid of expressing their "real" opinions, or probably both"
Good grief! We have been thru this before: subscribers to those magazines are predominately commissioned officers, and predominately Republican. I would also guess that many - if not most - of them are not serving in Iraq.
The ones that are in Iraq are in an "interesting" position. What is the benefit of opposing something that you are stuck in the middle of? How does it affect your performance? If I was there, I would do anything in my power to foster a positive mental attitude in myself, and in those around me. And it would not be stupid or out of fear.
