I think what the president [Barack Obama] understands, and what he's trying to do, is that we have to support the Arab and Kurdish fighters on the ground who are actually doing the fighting.

In the days ahead, I will propose more ways for more Americans to get involved in national service and give back to our communities, because every one of us has a role to play in building the future we want.

I remember, particularly, a trip to Bosnia where the welcoming ceremony had to be moved inside because of sniper fire.

It is important to recognize the limited ability of the legal system to prescribe and enforce the quality of social arrangements.

I think we're all safer when the police respect the communities they're supposed to serve, and the communities respect the law.

To Barack and Michelle Obama - America owes you an enormous debt of gratitude.

I do agree that in particular, Turkey and the Gulf nations have got to make up their minds. Are they going to stand with us against this kind of jihadi radicalism or not? And there are many ways of doing it. They can provide forces. They can provide resources. But they need to be absolutely clear about where they stand.
