Without question, we need to disarm Saddam Hussein. He is a brutal, murderous dictator, leading an oppressive regime ... He presents a particularly grievous threat because he is so consistently prone to miscalculation ... And now he is miscalculating America's response to his continued deceit and his consistent grasp for weapons of mass destruction ... So the threat of Saddam Hussein with weapons of mass destruction is real.

We have to create a process which has legitimacy for the people of Syria. And we have to have a process where the Russians and the Iranians and the neighbors - all of them, Saudis, Turks, Qataris, a very complicated brew - that you have to bring them together and they can find agreement. That's the fundamental premise of the Geneva Communique that you will have, by mutual consent, a process of transition.

I will never conduct a war or start a war because we want to; the United States of America should only go to war because we have to. And if you live by that guidance, you'll never have veterans throwing away their medals or standing up in protest.

The world has to save Syria. I mean, this has dramatic implications for the entire region, globally.

If the choice is one-state, Israel can either be Jewish or Democratic. It cannot be both.

We need a leader who has a sense of balance, an understanding of the ebb and flow of history and a sense of our country's unique place in it. This is a foreign policy debate, and you cannot conduct foreign policy without a sense of what we are fighting for. And any President who can reduce the conduct of this country's affairs to a morning's attack by a bunch of demented fascists does not, in my view, understand what this great nation is all about.

We need a new approach to national security - a bold, progressive internationalism that stands in stark contrast to the too often belligerent and myopic unilateralism of the Bush Administration.
