Americans are split over whether the US should quit NATO after allies refused to help secure the Strait of Hormuz, a new Daily Mail/JL Partners poll of 1,000 registered voters finds.

President Trump has ripped into NATO allies for doing 'nothing' to help secure Hormuz during his war on Iran - and has threatened to pull the US out of the alliance.

But voters are torn on whether the President should make good on his threat. 

While 33 percent of all respondents say they would support leaving the alliance over the NATO-Strait standoff, 33 percent remain opposed to a withdrawal.

However, the data reveal a partisan divide: a clear majority of 57 percent of Republicans back the idea of pulling out of NATO if allies continue to withhold military aid in the Persian Gulf.

The 'Hormuz fury' has also sparked a debate over how to handle the economic fallout of the blockade. Four-in-ten (41 percent) of US voters see the reopening of the Strait of Hormuz with fees for ships as a bad outcome overall. 

The margin of error for the poll is 3.1 percent.

Trump's own approval rating has dropped three points, according to the Daily Mail survey, as voters remain wary of the war. Trump's approval rating stands at 43 percent, a slide from the last survey in late March. 

During a high-stakes encounter hours after a closed-door meeting with the President, the Daily Mail cornered NATO Secretary-General Mark Rutte with several inquiries.  

Rutte was asked Thursday by the Daily Mail whether he truly believes Trump will maintain America's commitment to NATO - and if he still views the President as 'Daddy'?

Through laughter, the politician tried to explain what he meant by 'Daddy' – saying it was a 'language problem' on his end. 

'It follows me a little bit, I can assure you,' Rutte explained further, saying it weighed on him. 'You make mistakes, and this is when you are not a native speaker – sorry for that.'

Rutte said on Thursday that member countries are doing everything Trump had requested to strengthen the military alliance, even if some were initially 'a bit slow' to provide support to the US amid its war with Iran.

'Some allies were a bit slow, to say the least,' Rutte said. 'In fairness, they were also a bit surprised.'

Rutte described a 'mindset shift' in Europe which he claimed was evidenced by the UK leading a coalition of countries to help reopen the Strait of Hormuz.

Trump told Rutte that words from NATO allies are no longer enough - he wants action.

Writing on Truth Social on Thursday, Trump said: 'None of these people, including our own, very disappointing, NATO, understood anything unless they have pressure placed upon them!!!'

During his speech, Rutte heaped praise on Trump as he admitted Europe must step up its spending on the alliance.

He said: 'We must applaud Trump for his bold leadership and vision'.

France, Spain and other nations, however, agreed to help with an international coalition to open the Strait of Hormuz when the conflict ends.

Trump's frustration with NATO has been building. It deepened after Germany, France, the UK, Sweden, Norway, the Netherlands and Finland deployed troops to Greenland in a show of solidarity against his attempts to acquire the territory.

NATO chief Rutte acknowledged the alliance is in 'a period of profound change' with no return to the status quo, while pledging that Europe would no longer be 'unhealthily reliant' on the US - and that America would have allies 'capable and ready, willing and able to defend' NATO's security.

But the bloc faces a stark reality: meet Trump's demands, or risk losing American backing in the future.
