If you get an infection, you get a fever; the fever is your body dealing with the infection. If you get traumatized, your mind and your brain have a reaction to that trauma. If you're not dreaming about it, something's probably wrong.

A grenade launcher will easily take out a tank; a Molotov cocktail placed in its air intake will destroy one as well.

I would never want to pass a law limiting freedom of speech, but that doesn't mean we have to condone statements that undermine basic national unity and respect. Imagine being asked to defend a country where some citizens say the man in the White House isn't their president. Or a major presidential contender accuses the commander in chief of not even being a U.S. citizen. Those kinds of statements erode trust in our democracy, and it's up to both parties to publicly reject them. We have to restore confidence that we are a nation that loves and believes in itself.

Of the primary emotions, fear is the one that bears most directly on survival. Children show fear. Adults try not to, maybe because it's shameful, or, in some circumstances, dangerous. The fear response is automatic, though, and your body runs through its reflexes whether you want it to or not.

The only thing that makes battle psychologically tolerable is the brotherhood among soldiers. You need each other to get by.

The negative effects of combat were nightmares, and I'd get jumpy around certain noises and stuff, but you'd have that after a car accident or a bad divorce. Life's filled with trauma. You don't need to go to war to find it it's going to find you. We all deal with it, and the effects go away after awhile. At least they did for me.

The attacks of 9/11 came out of Afghanistan. It was a failed state, a rogue nation. That's why al Qaeda was there in the first place.
