Iran live updates: US blockade of Iran's Strait of Hormuz ports to begin Monday

President Donald Trump said at the White House Easter Egg Roll on Monday that Americans against the war with Iran are "foolish," saying the conflict is "about one thing: Iran cannot have a nuclear weapon."

"We are obliterating their country. And I hate to do it, but we're obliterating," he said.

Trump said if he had his "choice," he'd "take the oil."

"Because it's there for the taking -- there's not a thing they can do about it," Trump said. "Unfortunately, the American people would like to see us come home. If it were up to me, I'd take the oil, I'd keep the oil, I'd make plenty of money. And I'd also take care of the people of Iran."

"If it were up to me I'd like to keep the oil, I just don't think the people of the United States would really understand," he added.

Iranian foreign ministry spokesman Esmaeil Baqaei said that Iran has been engaging in talks with Oman on examining "a procedure for the safe passage of vessels through the Strait of Hormuz."

Baqaei said the talks with Oman have been held at the level of deputy foreign ministers.

"We think these talks will continue until coming to a conclusion," he added.

Referring to President Donald Trump's deadline threat, Baqaei said Iranians will not be "subjugated" by deadlines in defending their country.

Trump threatened to target Iran's power plants and bridges unless the regime opens the Strait of Hormuz by Tuesday night.

Asked about reports of a draft proposal that includes a 45-day ceasefire and reopening of the Strait of Hormuz, a White House official told ABC News on Monday, "This is one of many ideas, and POTUS has not signed off on it. Operation Epic Fury continues. President Trump will speak more at 1 p.m."

The Associated Press reported on Monday that the U.S. and Iran had both received a draft proposal calling for a 45-day ceasefire and the reopening of the Strait of Hormuz to facilitate subsequent full peace talks. ABC News has not confirmed the reported plan.

Iran will not accept a ceasefire without "suitable guarantees," a Pakistani security official told ABC News on Monday.

"Any process for a ceasefire without suitable guarantees and assurances would be unacceptable to Iran," the official said, responding to reports that mediators are pushing for a ceasefire to halt the U.S.-Israel war against Iran.
