Both sides of the aisle - Republican and Democrat - have been unwilling and afraid to address the deficit, and someone's got to.

I think that if you believe in regime change, you're mistaken. In 2013, we put 600 tons of weapons - us, Saudi Arabia, and Qatar - into the war against [Bashar] Assad. By pushing Assad back, we did create a safe space.

Roll back federal spending to 2008 levels.

We have Islamic rebels [in Syria] who've been eating the hearts or organs of their enemies. We have priests that have been killed. We have Christian villages that have been razed by Islamic rebels. We have Islamic rebels who say they don't recognize Israel and would just as soon attack Israel as [Bashar] Assad. So really, I see no clear-cut American interest, and I'm afraid that sometimes things unravel, and the situation could become less stable and not more stable.

We shouldn't have a program where we just say that we're going to take care of the world's refugees. Nobody in the Middle East is doing anything. Saudi Arabia, Qatar, Kuwait - all the Gulf nations are doing nothing.
