On Monday night, as the Democrats were kicking off their convention in Philadelphia, Donald Trump spoke at an event in Winston-Salem, N.C. Over the course of his speech, he addressed his recent comments about how and when he'd back up allies in the North Atlantic Treaty Organization and, more broadly, when the United States would intervene overseas.

NATO. They ask me about NATO. Right? You saw that the other day, "Meet the Press."

"Well, I hear you want to give up NATO..." I don't want to give up NATO. I like ... NATO's fine. But they gotta pay. They gotta pay.

So we have all of these countries, and they're not paying. They're not paying. And we're protecting them.

And the question is: "If such-and-such a country were attacked, are you willing to start World War 3?" Because that's essentially what's happening. They don't pay.

They say, "Well, we have a treaty!" So they have these articles: "Donald Trump wants to give up NATO." No no no. I don't want to give up anything. I want them to pay.

We're a country. It's not 40 years ago, 50 years ago. And now, most people in this audience don't even know, that we're protecting Japan, Chi-- we're protecting Germany! Nothing but money.

We're protecting Saudi Arabia. If we weren't around, Saudi Arabia, Saudi Arabia wouldn't be around for two weeks. We protect Saudi Arabia. They don't pay us what that should be paying. We're losing everything.

Folks, we lose on everything.

We protect South Korea. We have 28,000 soldiers on the line, against the maniac on the right. We have 28,000 soldiers against North Korea, separated. Pretty dangerous stuff, considering he's got a million-person army. Pretty dangerous stuff.

So we're doing all this, and yet they're paying us a fraction of what it is.

I saw it with Japan. And by the way, I think it's fine -- but they've got to pay us. We don't have the money. They gotta pay us. And they will pay us if the right person asks. If the right person asks. They will. They will.

Do you have any idea the difference that makes for our country if we get countries to take care of us the way they should.

We had a general recently, because we've been doing this, and he said, "Mr. Trump doesn't understand that Japan is paying almost 50 percent of the cost of what we do for them." And I said, why not 100 percent? Why? Tell me why. Tell me why.

Folks, we're run by incompetent people and it's going to end. And it's going to end soon. Because people aren't taking it anymore.

Now, when I talk about we're going to protect Japan, which is great, now, you always have to be prepared to walk. And I said, in one of the articles, they said, "Now what would happen if they didn't pay." I said, "We have to walk."

Hillary Clinton said, "He wants to walk from Japan!" Now, see, what she did, she makes it impossible to negotiate. She's not a negotiator. She's a fool. She's a fool. No, she's a fool.

Because when you tell Japan -- very smart people, great people, I have many friends there -- but when you say you're not prepared to walk, you'll never walk? So she said, "How dare he say that! We will never walk!"

Then they're never going to pay us. We may have to walk! Folks, we may have to walk.

But -- the same thing with Germany. We're spending a fortune in Germany. Same thing with Saudi Arabia. Let me tell you. Saudi Arabia? So we'll say this: "Folks, you gotta pay us. You gotta pay us. Sorry."

They're gonna say no. Bye-bye! Within two days, they're calling back, "Get back over here, we'll pay you whatever the hell you want."

OK? One hundred percent.

But when we have a fool -- when we have a fool -- an absolute fool like Hillary Clinton, saying, "we will never abandon, we will never leave" -- they're not going to pay. And we don't have the money to take care of every nation in the world.

We don't have the money. And the same thing with the NATO nations, and they'll pay and they'll all pay probably -- and if they don't pay, you walk! And that's OK, too. That's the way it works, folks. That's the way it works.
