When I was in the White House, I was confronted with the challenge of the Cold War. Both the Soviet Union and I had 30,000 nuclear weapons that could destroy the entire earth and I had to maintain the peace.

Then when [ISIS] moved into Iraq, the Sunni Muslims didn’t object to their being there and about a third of the territory in Iraq was abandoned.

One of the greatest concerns that I had when I became President was the vast array of nuclear weapons in the arsenals of the United States and the Soviet Union and a few other countries, and also the great proliferation of conventional weapons, non-nuclear weapons, particularly as a tremendous burden on the economies of developing or very poor countries.

Our American values are not luxuries but necessities, not the salt in our bread, but the bread itself. Our common vision of a free and just society is our greatest source of cohesion at home and strength abroad, greater than the bounty of our material blessings.

If I were president, I'd be very glad to see the Palestinians have a nation recognized by the United Nations. There's no downside to it.

I don't think there's going to be peace as long as Israel is occupying land that belongs to the Palestinians, to Lebanon and to Syria.

For the first time in the history of our country the majority of our people believe that the next five years will be worse than the past five years.
