Iran has given an updated proposal for a deal to end the war, but the White House believes it is not a meaningful improvement and is insufficient for a deal, a senior U.S. official and a source briefed on the issue told Axios.

U.S. officials say President Trump wants a deal to end the war, but is considering resuming it due to Iran's rejection of many of his demands and refusal to make meaningful concessions on its nuclear program.
Trump is expected to convene his top national security team in the Situation Room on Tuesday to discuss military options, two U.S. officials said.
The senior U.S. official said that if Iran won't shift its position, the U.S. will have to continue the negotiations "through bombs."
Trump told Axios in a phone call on Sunday, before the U.S. had received Iran's later offer, that "the clock is ticking" and if Iran doesn't show flexibility, "they are going to get hit much harder."
The senior U.S. official said the Iranian counter-proposal, which was shared with the U.S. on Sunday night via the Pakistani mediators, has only token improvements on the last version.
"We are really not making a lot of progress. We are at a very serious place today. The pressure is on them to be responsive in the right way," the senior U.S. official said.
