Donald Trump Leaders around the world said Friday that President Donald Trump's Iran plan could isolate America on the global stage.
Anything short of the U.S. failing to stand by the nuclear agreement would mean chaos, the leaders said.
"Such actions will certainly damage the atmosphere of predictability, security, stability and non-proliferation in the entire world," said Dmitry Peskov, a Kremlin spokesman.
"This can seriously worsen the situation around Iran nuclear deal. Such possible actions of the American side will have very, very, very negative consequences," he added.
Ali Larijani, the speaker of Iran's parliament, said if the U.S. withdraws from the deal, so will Iran.
"They seem to have begun certain movements, which in the long run will cause a lack of order on the international arena," Larijani said on Friday, according to TASS, a Russian state news agency.
Trump is punting the Iran nuclear deal to Congress, declining to certify that the Islamic state is in compliance with the agreement and placing pressure on lawmakers to decide whether to end the deal.
