Right now, Russia's future should be wedded to Europe. Why they see NATO as a threat is beyond me. Clearly, NATO is not a threat.

Demonstrate to the world there is "No Better Friend, No Worse Enemy" than a U.S. Marine.

In this age, I don't care how tactically or operationally brilliant you are, if you cannot create harmony - even vicious harmony - on the battlefield based on trust across service lines, across coalition and national lines, and across civilian/military lines, you need to go home, because your leadership is obsolete. We have got to have officers who can create harmony across all those lines.

When you're in operations, the best thing you can do at the top level is get the strategy right. You have to get the big ideas right, you have to determine what is the policy, what is the level of effort you're willing to commit to it? And then you delegate to those who have to execute that strategy to the appropriate level. What's the appropriate level? It's the level where people are trained and equipped to take decisions so we move swiftly against the enemy.

Anyone who kills women and children is not devout. ISIS cannot dress themselves up in false religious garb and say that somehow this message has dignity. We're going to strip them of any kind of legitimacy.

We do everything humanly possible, consistent with military necessity, taking many chances to avoid civilian casualties, at all costs.

No war is over until the enemy says it's over. We may think it over, we may declare it over, but in fact, the enemy gets a vote.
