A possible US withdrawal from the Iran nuclear deal would have negative consequences, Kremlin spokesman Dmitry Peskov said Monday.

“[Russian] President [Vladimir] Putin has repeatedly spoken about the importance of the agreement on the so-called Iranian nuclear dossier. Of course, the withdrawal of one of the countries, especially a key country like the United States, from this agreement will only have negative consequences,” Peskov told reporters, adding that Moscow was trying to analyze it.

Kremlin’s statement comes amid rumors of the possible US withdrawal from the Iranian nuclear deal fueled by Trump’s controversial remark during a dinner for military commanders attended by reporters. Trump puzzled the White House media pool on Thursday evening, referring to the time during which he posed for a photo with the country’s military leaders as “the calm before the storm.”

The statement prompted media speculations, saying that the US is going to withdraw from the Iranian nuclear deal with The Washington Post reporting citing anonymous officials that Trump was expected to announce within a week that he would “decertify” the international nuclear deal with Iran because it was not in the US national interests.

On Saturday, Iran yet again defended the nuclear deal with the country’s president saying that Donald Trump cannot change the fact that the agreement is “irreversible.” Earlier in the day, China also voiced strong support of the agreement.

The historic nuclear deal between the leading global nations, including the United States, Russia, France, Germany, China, the United Kingdom, and Iran was signed on July 14, 2015 after years of high-scale tension over the nuclear program of the Islamic Republic.

The Joint Comprehensive Plan of Action (JCPOA),  commonly referred to as the Iran Nuclear Deal, was signed in July 2015 by Iran and the P5+1 group of nations comprised of the United States, Russia, China, France and the United Kingdom plus Germany after years of diplomatic work.

Donald Trump called the JCPOA, negotiated under President Barack Obama’s watch “an embarrassment” to the United States during his speech to the UN General Assemblyand has repeatedly criticized it during his presidential and election campaign.
