Iranian President Hassan Rouhani predicted Wednesday that the United States would eventually rejoin an international nuclear deal, saying talks this week at the United Nations showed his counterpart Donald Trump's isolation.

"The United States of America one day, sooner or later, will come back. This cannot be continued," Rouhani told a news conference. "We are not isolated; America is isolated," he said. Rouhani pointed to a session of the Security Council chaired by Trump earlier Wednesday, where the leaders of Britain and France backed the nuclear deal, as well as a statement by European powers who say they will find ways to continue business with Iran and evade impending sanctions.
