We owe our troops the opportunity to serve in the best-planned, best-equipped, and best-led military force in the world, and we owe them the peace of mind that comes from knowing that they and their families will be taken care of if they sacrifice life, limb or the ability to sleep without war's nightmares. We owe them not just thanks and best wishes, but action, and action in our nation's capital.

Capturing Saddam Hussein and ensuring that this brutal dictator will never return to power is an important step toward stabilizing Iraq for the Iraqis. Let's also be clear: Our problems in Iraq have not been caused by one man, and this is a moment when the administration can and must launch a major effort to gain international support and win the peace.

America that has done more to support Israel than any other country cannot be true to our own values if we allow a viable two-state solution to be destroyed before our own eyes.

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.

If Russia is there [in Syria] alone fighting them [ISIL], guess what? Russia becomes the target and Russia starts seeing - who knows - MANPADs will find their way in there, airplanes will fall out of the sky. They will become vilified. They'll become the new magnet, together with Assad, for the jihadis.

We deserve a president of the United States who will write laws for all Americans, not for campaign contributors. And I intend to be a president for all Americans who takes back the flag of our country because it doesn't belong to any party, doesn't belong to any president.

[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.
