Donald Trump has vowed to remain in Nato if EU nations 'treat America fairly.'
In an exclusive sit down with GB News presenter Nigel Farage, the former president of the United States slammed EU nations for 'taking advantage' and ordered them to 'pay up' to guarantee US support.
Trump has often criticised Nato and its members such as Germany, accusing them of not paying enough for their own defence and relying on Washington to protect them.
Nato is a collective defence between the US, Canada and twenty-eight European countries and it revolves around the idea that an attack on one member is considered an attack on all of them.
Speaking to Trump, Farage said: "You said this back in 2017 and 18 when you were president you visited Brussels, and you commented that the Russians can do whatever they want if these countries don't pay. You said it again recently. That's now being used."
Trump responded: "They can use it, I don't care if they use it. Because what I'm saying is a form of negotiation. Why should we guard these countries that have a lot of money and the United States was paying for most of Nato? When I went there, I had already had it out with them [in the past].

"They then stopped paying again. But now they're paying because of those comments that you saw two, three weeks ago [from me when I visited]. I don't know if you know, but a lot of money's come in since those comments were made."
Trump has often accused other Nato members of not paying their dues, giving the impression that the alliance is like a club with membership fees.
In 2017, when he was President he chided Nato member countries directly for not meeting their financial commitments to the alliance and declined to reiterate US commitment to the alliance’s mutual defence pledge.
The former president told Farage: "Nato was not paying, I went to the first meeting early in my administration and I saw what was going on and I said 'you're gonna have to pay your bills everybody.' Then at the second meeting, I hit them hard.
"The question was then asked by the head of a major country in front of everyone else 'So if we don't pay our bills, are you going to protect us from Russia?'
He blasted that if the NATO countries don't start paying their wall "America will not defend you"

"I said 'you mean you're delinquent? You're not paying the bills? Then no, I'm not going to pay you we're not going to do it.
"We're not going to defend you if you're not paying your bills. It's very simple. And hundreds of billions of dollars came flowing in."
"Nato became strong because of me. Now Nato has to treat the US fairly because if it wasn't for the United States, Nato wouldn't even exist. They took advantage of us like most countries do," Trump explained.
Farage then asked him: "If they start to pay their bills properly and the club is fair are places like Poland going to be defended? Will America be there?"

To which the former president replied: "Yes. But the United States should pay its fair share, not everybody else's fair share."
Farage said: "Fair enough." Trump told the GB News host: "I believe that the United States was paying 90 per cent of Nato, that could be 100 per cent.
"It was the most unfair thing and don't forget, it's more important to them than it is to us. We have an ocean between some problems.
"They will take advantage. They took advantage of us on trade, they took advantage on the military.
Nigel Farage asked him: "So if they start to play fair, America's there?"
The former President Trump responded: "Yes. 100 per cent."
