WATCH: White House addresses Strait of Hormuz opening, Trump's 'civilization' threat

The White House said Wednesday that President Donald Trump is clear that the ceasefire means no Iranian tolls through the Strait of Hormuz.

The ceasefire requires a "free" reopening of the Strait of Hormuz, which includes no tolls imposed by Iran, said White House press secretary Karoline Leavitt, describing Trump's thinking.

A regional official had said on condition of anonymity to discuss internal deliberations that the ceasefire plans included allowing both Iran and Oman to charge new fees to ships transiting through the strait.

Leavitt referenced Trump's Truth Social post from Tuesday in which he said the agreement was conditional on the "COMPLETE, IMMEDIATE, and SAFE OPENING" of the strait. She added that "that's very plain language and it should be taken at face value."

The White House says Iran presented a 'new, modified peace plan that it is able to 'align with our own, 15-point proposal'

Leavitt said that "the Iranians originally put forward a 10-point plan that was fundamentally unserious, unacceptable and completely discarded," and that it was "literally thrown in the garbage by Trump."

But, she said, Iranian authorities on Tuesday presented a new plan that will become a workable basis for negotiations to bring the Iran war to an end.

Leavitt said the new version of the Iranian plan can now "align with our own, 15-point proposal" for peace.

Vance will lead U.S. delegation to Islamabad for talks with Iran

The White House confirmed that U.S. Vice President JD Vance will lead the U.S. negotiating team in talks with Iran aimed at finding a permanent end to war.

Vance will lead the delegation, which is also expected to include special envoy Steve Witkoff and Trump's son-in-law Jared Kushner, for the talks that are expected to begin Friday in Islamabad, according to White House press secretary Karoline Leavitt.

"Vice President Vance has played a very significant and a key role in this since the very beginning," Leavitt told reporters during a White House press briefing. "Of course, he's the president's right hand man. He is the vice president of the United States. He's been involved in all of these discussions."

White House defends Trump's language threatening 'a whole civilization'

Asked about Trump's threat to annihilate Iranian civilization, Press Secretary Karoline Leavitt defended it as a "very strong threat that led to results."

"I think it was a very, very strong threat from the president of the United States that led the Iranian regime to cave to their knees and ask for a ceasefire and agree to reopening the Strait of Hormuz," Leavitt said at a press briefing on Wednesday.

She said any suggestion that Iran had the moral high ground was "insulting."

Before a ceasefire was announced, Trump had threatened destruction in Iran if it did not reopen the strait, saying "a whole civilization will die tonight, never to be brought back again."

White House shrugs off NATO's pledge to ensure freedom of navigation through a reopened Strait of Hormuz

Leavitt was asked about NATO allies offering to contribute to keeping the strait open, but said the alliance hasn't done enough to support U.S. and Israel's war in Iran.

"They were tested and they failed," Levitt said, reading from a past Trump quote on NATO.

She added: "NATO turned their backs on the American people over the course of the last six weeks."

Those comments came as Trump was meeting with NATO Secretary-General Mark Rutte at the White House later Wednesday.

Trump expected to raise possibility of US leaving NATO in meeting with Rutte

The president earlier this month said that he was considering withdrawing the U.S. from NATO as he grumbled about the lack of support from members of the alliance in his war of choice against Iran.

The criticism from Trump follows years of complaining that the alliance's member countries aren't paying enough for their own defense. Trump is set to host Secretary-General Mark Rutte for talks at the White House later this afternoon.

"It's something the president has discussed, and I think it's something the president will be discussing in a couple of hours with Secretary General Rutte," said Leavitt, when asked if Trump is still considering leaving the 32-member alliance.
