Interesting: Mr. Trump is sounding a bit like Senator Rand Paul. Personally, I agree with most of what he's saying in this case.

Trump questions need for NATO, outlines noninterventionist foreign policy
Donald Trump outlined an unabashedly noninterventionist approach to world affairs Monday, telling The Washington Post's editorial board that he questions the need for the North Atlantic Treaty Organization, which has formed the backbone of Western security policies since the Cold War.

"I do think it's a different world today, and I don't think we should be nation-building anymore," Trump said. "I think it's proven not to work, and we have a different country than we did then. We have $19 trillion in debt. We're sitting, probably, on a bubble. And it's a bubble that if it breaks, it's going to be very nasty. I just think we have to rebuild our country."

He added: "I watched as we built schools in Iraq and they're blown up. We build another one, we get blown up. We rebuild it three times and yet we can't build a school in Brooklyn. We have no money for education because we can't build in our own country. At what point do you say, 'Hey, we have to take care of ourselves?' So, I know the outer world exists and I'll be very cognizant of that. But at the same time, our country is disintegrating, large sections of it, especially the inner cities."

Trump said that U.S. involvement in NATO may need to be significantly diminished in the coming years, breaking with nearly seven decades of consensus in Washington. "We certainly can't afford to do this anymore," Trump said, adding later, "NATO is costing us a fortune, and yes, we're protecting Europe with NATO, but we're spending a lot of money."
