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.

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."

A U.S. official and another source familiar with the negotiations told ABC News later on Monday that the draft of the deal on the table calls for a 45-day ceasefire, during which a permanent end to the war could be negotiated.

While the White House has already said that President Donald Trump has not committed to anything, the administration’s key demands call for Iran to give up what the regime views as its main points of leverage: control over the Strait of Hormuz and its stockpile of highly enriched uranium. So far, Iran has shown little to no flexibility on those terms, both sources said.

The sources added that mediators are attempting to see if confidence-building measures might bring both sides closer to an agreement, but they are working on a very tight timeframe as Trump’s Tuesday deadline approaches.

Mediators have floated the idea that perhaps access to the Strait of Hormuz and the elimination of Iran’s uranium stockpile could be fully resolved after ceasefire is reached. The U.S. official said it appeared highly unlikely the Trump administration could be convinced to accept those terms -- particularly concerning the Strait of Hormuz.

Iran has signaled that it will not accept the mediators’ proposal as it stands, and submitted its own 10-point plan in response to the draft ceasefire agreement.

At least 3,546 people -- including 244 children-- have been killed in Iran since the war began, according to the U.S.-based Human Rights Activists News Agency.

At least 1,219 military personnel are included in the death toll, HRANA said.
