I think as we look at this problem of ISIS, it's more than just an army. It's also a fight about ideas. And we have got to dry up their recruiting. We have got to dry up their fundraising. The way we intend to do it is to humiliate them, to divorce them from any nation giving them protection, and humiliating their message of hatred, of violence. Anyone who kills women and children is not devout. They have - they cannot dress themselves up in false religious garb and say that somehow this message has dignity.

We have the most skillful, firecest, and certainly the most ethical ground forces in the world... I'm not saying we have to commit right now, but certainly don't pull it off the table.

Treachery has existed as long as there's been warfare, and there's always been a few people that you couldn't trust.

It is mostly a matter of wills. Whose will is going to break first? Ours or the enemy's?

For the mission's sake, our country's sake, and the sake of the men who carried the Division's colors in the past battles - who fought for life and never lost their nerve - carry out your mission and keep your honor clean. Demonstrate to the world there is "No Better Friend, No Worse Enemy" than a U.S. Marine.

The most important six inches on the battlefield is between your ears.
