Russia suggested on Wednesday that reaching a new Iran nuclear deal to appease the U.S. might not be possible.

“We know that the nuclear deal was the meticulous work of a number of countries. Is it possible to repeat that work — that is a question,” Kremlin spokesman Dmitry Peskov told reporters, according to Reuters.

“We do not know what is being talked about, we support the nuclear deal as it is today. We think that there are no alternatives," he added.

"We're looking forward to doing something but it has to be done and it has to be done strongly," Trump said during French President Emmanuel Macron's state visit. "We're fairly close to understanding each other. Our one on one went very well."

“Nobody knows what I’m going to do on the 12th, although Mr. President, you have a pretty good idea,” Trump said during a joint press conference with Macron, referring to a May deadline the president has set.

Macron and other European leaders are pushing Trump to remain in the multination deal, saying it is the best hope to prevent Tehran from acquiring nuclear weapons.

Trump has slammed the Obama-era deal, however, referring to it as the "the worst deal ever negotiated" and an "embarrassment."

Iranian President Hassan Rouhani warned the Trump administration on Tuesday that Tehran will not accept any changes or additions to the nuclear agreement.

Rouhani told Macron "explicitly that we will not add anything to the deal or remove anything from it, even one sentence. The nuclear deal is the nuclear deal," according to The Associated Press.
