The biggest problem this world has today is not President [Barack] Obama with global warming, which is inconceivable, this is what he's saying. The biggest problem we have is nuclear - nuclear proliferation and having some maniac, having some madman go out and get a nuclear weapon. That's in my opinion, that is the single biggest problem that our country faces.

In America, our jobs are being taken away from us. Companies, as we speak, are signing documents with Mexico and other places to move.

So what I'm doing is a large tax cut especially for the middle class and they're gonna- we're going to have a dynamic country. We're going to have dynamic economics. And it's going to be something really special. And people are going back to work.

If we have a great relationship with Russia and other countries, and if we go after ISIS together, which has to be stopped - that's an evil that has to be stopped - I will consider that a good thing, not a bad thing.
