NEW YORK — Iranian President Hassan Rouhani, speaking at a press conference here today, portrayed the Donald Trump administration as inexperienced and the United States as isolated at the United Nations Security Council over its decision to withdraw from the 2015 Iran nuclear deal. He suggested Washington may eventually decide to come back to the deal.

“We are not isolated,” Rouhani, speaking in Persian with English translation to Iranian and foreign journalists at a hotel conference room across from the UN, said today. “As a matter of fact, America is isolated.”

“On the Security Council, everyone expressed support for the JCPOA, and said the path chosen by the US is the wrong path,” Rouhani said, referring to the Joint Comprehensive Plan of Action, the formal name of the 2015 Iran nuclear deal. “The Americans are alone and isolated, and faced with many challenges from its own presence and security.”

“The USA made a mistake,” Rouhani said. “Either they will come back [to the deal], or they will continue down the path of this mistake. This cannot continue.”
