We know that russians are deeply engaged in supporting Assad because they want to have a place in the Middle East. They have a naval base, they have an air base in Syria.

When I spend my time out on the campaign trail, it's usually about what I can do for somebody else. I don't like talking about myself, I don't like the whole atmosphere of how people are judged in American politics too often as to what you say instead of what you do. And so for me it's always about what can I do for you? How can I help you?

What [Barack Obama] and I did was to say clearly what we're doing, all the bluster, all of the sanctions, that are just imposed by the American government haven't had much impact.Let's see if we can put together an international coalition to really cripple Iran, and then maybe we can begin a negotiation, and that's what I did. It was difficult. We had to get China and Russia on board, and not just get them on board by signing a piece of paper.

We have to figure out how to deal with Iran as the principal state sponsor of terrorism in the world.

The cavalier casual way that Donald Trump talks about nuclear weapons is not only frightening but it goes counter to more than 70 years of bipartisan, presidential leadership of Republicans and Democrats who believed that we have to prevent other countries from getting nuclear weapons and we have to do what we can to decrease the number of nuclear weapons in the world.

I'm a proud product of the American middle class.

I thought using one device would be simpler.
