Trump: Nuclear Is a "Horror Show," "We Can't Afford" NATO

GOP presidential front-runner Donald Trump tells John Dickerson on "Face The Nation" that he believes the U.S. can’t afford to continue protecting NATO allies overseas. “Now, at some point, they may have to protect themselves,” Trump says. “Do I like that? Not particularly. But we cannot afford it as a country.” Dickerson further probes Trump's thoughts on foreign policy.

JOHN DICKERSON: You met with your foreign policy team in your hotel in Washington. What did you ask them?

DONALD TRUMP: More than anything else I discussed nuclear. To me, the single biggest problem that this world has -- and we'll knock out ISIS fast and we'll do a lot of things -- but the single biggest problem the world has is nuclear.

DICKERSON: In what way do you mean that's the biggest?

TRUMP: I think if somebody gets nuclear weapons, that's a disaster.

...

DICKERSON: Which country of all the ones...?

TRUMP: I think it could be many people. It's not even countries. It's splinter groups.
