Confronting climate change is, in the long run, one of the greatest challenges that we face, and you can see this duty or responsibility laid down in scriptures, clearly.

[Bashar] Assad himself has said on several occasions recently that if the people of Syria don't believe I should be there in the future, then I would step - I would leave. He has said it. He has, on occasion, hinted that he wants a political settlement of one kind or another. I think it's up to his supporters, his strongest supporters, to make it clear to him that if you're going to save Syria, Assad has made a set of choices - barrel bombing children, gassing his people, torturing his people, engaging in starvation as a tactic of war.

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.

There is a much cheaper way, less complicated way to bring Iraq and Saddam Hussein to its knees: it is simply to send the Bush economic team over there and let them run the country.

As a public person, I've always tried to reflect what is embodied in our defining ideals as a nation about equality and fairness and justice and so forth.

What we need now is not just a regime change in Saddam Hussein and Iraq, but we need a regime change in the United States.

What remains unchanged is the principle, which is that we do not launch wars without overwelming reasons, and overwhelming alliances, and without overwhelming force.
