I think that by arming the allies of ISIS, the Islamic rebels against [Bashar] Assad, that we created a safe space or made that space bigger for ISIS to grow.

I've thought for some time that the answer to a lot of problems in the Middle East, including Iran, include an active role with Russia. And I think, in some ways, we've taken show votes in the U.N. that are guaranteed to failure before we take them.

A free society will abide unofficial, private discrimination, even when that means allowing hate-filled groups to exclude people based on the color of their skin.

The idea of foreign policy realism, I think, fits more neatly with President Trump. And with John McCain, the neoconservative label of let's make the world safe for democracy and we're going to topple every regime hasn't worked.

The problem or the fundamental flaw of Obamacare was that they put regulations on the insurance, about 12 regulations, which increased the cost of the insurance. And so President Obama wanted to help poor, working-class people, but he actually hurts them by making the insurance too expensive to want to buy. I had someone at the house just recently was doing some work, and he said: "Oh, my son doesn't have insurance, he's paying the penalty because it's too expensive."

You can be strong without being involved in every single civil war around the world.

I think that there is a bipartisan consensus that's incorrect that we should have the whole world be in NATO. For example, if we had Ukraine and Georgia in NATO - and this is something McCain and the other neocons have advocated for - we would be at war now because Russia has invaded both of them.
