So the threat of Saddam Hussein with weapons of mass destruction is real.

Think about this: terrorism, epidemics, poverty, the proliferation of weapons of mass destruction-all challenges that know no borders-the reality is that climate change ranks right up there with every single one of them.

No one is going to question my commitment to the defence of our nation. I don't know what it is these Republicans, who didn't serve in any war, have against those of us who are Democrats who did.

I don't think losing 3 million jobs, having deficits as far as the eye can go, having 2 million people lose their health insurance, turning your back on kids in schools and not funding No Child Left Behind represents a vision.

The big hang-up was George Bush wanted to get life lines, you know, so he could call somebody.

[Bashar] Assad has made a series of choices ever since then that is literally destroying his country.

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.
