President Donald Trump has sent shockwaves through the world after threatening to pull the United States out of NATO.

Trump is reportedly furious that allies failed to back US military action against the Iranian regime, according to an interview with Britain’s Daily Telegraph, and now is strongly considering tearing up the historic alliance.

The President didn’t hold back, branding the defense alliance a ‘paper tiger’ and chillingly warning that his decision to remove the United States is now ‘beyond reconsideration.’

‘Oh yes, I would say it’s beyond reconsideration,’ Trump explained. ‘I was never ​swayed ⁠by NATO. I always knew they were a paper ⁠tiger, ​and Putin knows ​that too, by the way.’

Trump admitted he has long harbored ‘doubts’ about NATO’s credibility; the lack of support in the Middle East appears to be the final straw for the commander in chief.

The move would effectively dismantle the world’s most powerful military bloc and leave Europe’s security in disarray. Founded in 1949, it’s currently a club of 32 countries across North America and Europe.

Since the start of the war with Iran, the US has unsuccessfully tried to lobby his NATO allies into joining the fight. 

The defense bloc has also been reluctant to help reopen the Strait of Hormuz, the vital waterway that ordinarily sees 20% of the world’s oil pass through every day.

Trump has warned he is strongly considering pulling the US out of NATO in his latest attack on the ‘paper tiger’ 

Following the establishment of a blockade, Iran has all but closed the Strait for weeks, sending oil and gas prices soaring. 

NATO’s reluctance on the fight in the Middle East appears to have irked Trump, who said: ‘Beyond not being there, it was actually hard to believe. I just think it should be automatic.

‘We’ve been there automatically, including Ukraine. Ukraine wasn’t our problem. It was a test, and we were there for them, and we would always have been there for them. [NATO] weren’t there for us.’

He also accused the UK being weak and accused the Royal Navy of not being in a good enough shape to fight: ‘You don’t even have a navy. You’re too old and had aircraft carriers that didn’t work.’
