Strategy equals execution. All the great ideas and visions in the world are worthless if they can't be implemented rapidly and efficiently. Good leaders delegate and empower others liberally, but they pay attention to details, every day.

When you decide to get involved in a military operation in a place like Syria, you've got to be prepared, as we learned from Iraq and Afghanistan, to become the government, and I'm not sure any country, either the United States or I don't hear of anyone else, who's willing to take on that responsibility.

We would like to see new leaders come forward who would be accountable and responsible, who would succeed in ending the terror and the violence. And it is up to the Palestinian people to judge who those new leaders should be.

I don't know that there is much the United States can do except work with the international community.

Don't let your ego get too close to your position, so that if your position gets shot down, your ego doesn't go with it.

Once the information is in the 40 to 70 range, go with your gut.

We are not trapped in what the science of management says we can do. We are capable of doing what the art of leadership says is possible.
