The campaign in Iraq illustrates the continuing progress of military technology and tactics, but if there is a single overriding lesson it must be this: American military power, especially when buttressed by Britain's, is virtually unchallengeable today. Take us on? Don't try! And that's not hubris, it's just plain fact.

Global warming is a matter of national security. Will we live in a world where we must fight our neighbors for fresh water and food? Or will we take the lead now and leave to our children and grandchildren a world better off than the one we inherited from our parents?

I like Hemingway and I like a lot Jewish writers (such as) Saul Bellow.

I don't think it's patriotic to put on a flight suit and prance around on the deck of an aircraft carrier looking for a photo op. We have a president of the United States who did not do his duty to take care of America. If you're patriotic, you do your duty.

I think you have to repudiate torture and I think you have to end what's going on at Guantanamo and you have to live up to American values. Basically you restore - what the American dream brought to the world stage was respect for the individual and the idea that people aren't pawns that rulers can push around but they have rights.

Working together, we can build a world in which the rule of law - not the rule of force - governs relations between states. A world in which leaders respect the rights of their people, and nations seek peace, not destruction or domination. And neither we nor anyone else should live in fear ever again.

As president of the United States, my top priority will be to keep America safe. We're going to go after the terrorist networks. We're going to go after Osama bin Laden. We are not going to live in fear in this country.
