The Army might screw you and your girlfriend might dump you and the enemy might kill you, but the shared commitment to safeguard one another’s lives is unnegotiable and only deepens with time. The willingness to die for another person is a form of love that even religions fail to inspire, and the experience of it changes a person profoundly.

Combat isn't where you might die -- though that does happen -- it's where you find out whether you get to keep on living. Don't underestimate the power of that revelation. Don't underestimate the things young men will wager in order to play that game one more time.

I’ve stopped war reporting. I realized that I’d answered all of my questions about war and about myself.

At 19, your brain hasn't finished wiring itself. So the first time you have a good friend die, most people don't go through that at 19. Soldiers do. They're facing life in this accelerated, compressed form, and a lot of times, they're not ready for it.

It's fun to have money, but the more money I get, the less interesting it becomes. If you don't have very much, you have to think about it. If you are starving, you become interested in food. If you are struggling to pay the bills, money becomes tragically important.

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.

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