WASHINGTON — US President Donald Trump, in a letter to Iran’s Supreme Leader Ayatollah Ali Khamenei proposing negotiations on a new nuclear deal, made clear that Iran has a two-month deadline to reach an agreement, a source familiar with the letter’s contents told CNN.

The directive comes as Trump has said he would like to reach a deal with Iran to gain more control over their nuclear capabilities. Trump’s Middle East envoy Steve Witkoff delivered the letter to the president of the United Arab Emirates Mohamed bin Zayed Al Nahyan while he was in Abu Dhabi last week, the source said. The UAE later gave the letter to the Iranians.

“President Trump made it clear to Ayatollah Khamenei that he wanted to resolve the dispute over Iran’s nuclear program diplomatically – and very soon – and if this was not possible, there would be other ways to resolve the dispute,” a spokesman for the National Security Council Brian Hughes said in a statement to CNN.

Axios was the first to report on the contents of the letter.

Trump also discussed a potential nuclear deal with Iran during his phone call with Russian President Vladimir Putin on Tuesday, according to a White House readout of the call.

The readout stated that Trump and Putin “spoke broadly about the Middle East as a region of potential cooperation to prevent future conflicts. They further discussed the need to stop proliferation of strategic weapons and will engage with others to ensure the broadest possible application.”

“The two leaders shared the view that Iran should never be in a position to destroy Israel,” the readout continued.

Earlier this month, Trump told Fox News that there “are two ways Iran can be handled: militarily, or you make a deal. I would prefer to make a deal, because I’m not looking to hurt Iran.”

“I said, ‘I hope you’re going to negotiate, because it’s going to be a lot better for Iran,’ and I think they want to get that letter – the alternative is we have to do something, because you can’t let them have a nuclear weapon,” Trump added.

It is unclear how the US would respond if Iran fails to enter direct talks regarding its nuclear program. However, senior US officials have not ruled out potential military action, whether through the US or Israel, on Iran’s nuclear facilities in the future.

During his first term in office, Trump withdrew from the Obama administration’s nuclear deal with Iran and ordered a US-led strike on Iranian commander Qasem Soleimani, leading to further backlash from Tehran.

Trump, in his second term, has returned to his “maximum pressure” campaign on Iran, in an effort to isolate the country economically and diplomatically.

Khamenei recently said calls for negotiations by “bully states” are aimed at dominating others, not resolving issues.

“The insistence on the part of some bully states on negotiations is not to resolve issues, but to dominate and impose their own expectations,” Khamenei said this month, as cited by Iranian state media outlets. — CNN
