WASHINGTON/TEL AVIV/CAIRO, April 2 -- The United States will end its war on Iran fairly soon and could return for "spot hits" if needed, President Donald Trump told Reuters on Wednesday, hours before he was scheduled to make a primetime address to the nation. Trump also said he would state in the speech Thursday morning that he was considering withdrawing the US from the NATO alliance. Asked when the United States would consider the Iran war over, Trump said: "I can't tell you exactly ... we're going to be out pretty quickly." US action had ensured Iran would not have nuclear arms, Trump said: "They won't have a nuclear weapon because they are incapable of that now, and then I'll leave, and I'll take everybody with me, and if we have to we'll come back to do spot hits." Global oil supplies were expected to be hit twice as hard this month as in March, the International Energy Agency said on Wednesday, underlining the urgent need for an end to the conflict Trump began with Israel on February 28. Trump said separately on social media that Iran had asked for a ceasefire but that he would not consider it until Tehran ceased blocking the Strait of Hormuz, a major fuel shipment route. Iran's Foreign Ministry spokesperson said Trump's remarks were "false and baseless." Iran's "New Regime President" has asked the US for a ceasefire, Trump said on Truth Social, possibly referring to comments Iran President Masoud Pezeshkian made Tuesday that the Islamic Republic has "the necessary will" to end this war - with certain guarantees. "We will consider when Hormuz Strait is open, free, and clear," Trump said. "Until then, we are blasting Iran into oblivion." Two security sources from Pakistan, which is mediating in the conflict, earlier told Reuters that Islamabad had proposed a temporary ceasefire to both sides but had not heard back from either. US Vice President JD Vance communicated with intermediaries from Pakistan about the Iran conflict as recently as Tuesday, a source briefed on the matter told Reuters on Wednesday. At Trump's direction, Vance signalled privately that Trump was open to a ceasefire as long as certain US demands were met, including reopening the Strait of Hormuz, the source said. Trump had signalled on Tuesday he could wind down the war in two to three weeks even without a deal, and scaled up threats to pull the US out of the NATO defence alliance if European states did not help stop Iran threatening the waterway. In his remarks to Reuters on Wednesday, Trump said he would express his disgust with NATO for what he considers the alliance's lack of support for US objectives in Iran. European states took pains to appear unruffled and France's junior army minister Alice Rufo said operations by NATO in the Strait of Hormuz would be a breach of international law. The conflict has killed thousands, spread across the region and caused unprecedented energy disruption. IEA head Fatih Birol said the main issue so far from Iran's effective closure of the Strait of Hormuz was the lack of jet fuel and diesel that was already a problem in Asia and would hit Europe in April or May. The head of European budget airline Ryanair said jet fuel supply to Europe could be disrupted from June....
