Trump Withdraws U.S. From ‘One-Sided’ Iran Nuclear Deal

The response from Iran itself, however, was muted. President Hassan Rouhani declared that the Iranians intended to abide by the terms of the deal, and he criticized Mr. Trump for his history of not honoring international treaties. Mr. Trump won strong backing from Saudi Arabia and Israel, whose leader, Prime Minister Benjamin Netanyahu, hailed him for a “historic move” and “courageous leadership.”

Three times previously, the president’s aides had persuaded him not to dismantle the Iran deal. But Mr. Trump made clear that his patience had worn thin, and with a new, more hawkish cohort of advisers — led by Secretary of State Mike Pompeo and the national security adviser, John R. Bolton — the president faced less internal resistance than earlier in his administration.

While Mr. Trump had long scorned the Iran deal, threatening repeatedly to rip it up during the 2016 presidential race, his impulse to act now was reinforced by what he views as the success of his policy toward North Korea. He has told aides and foreign leaders that his policy of maximum pressure had forced Mr. Kim to the bargaining table, and that a similar policy of overwhelming pressure would enable the United States to extract a better deal from Iran.

As Mr. Trump abandoned one diplomatic project, he accelerated another — announcing that Mr. Pompeo was flying to Pyongyang, the capital of North Korea, to continue discussions with Mr. Kim about the upcoming summit meeting. He expressed hope that three Americans who are detained in the North would be released soon.

“The message to North Korea,” Mr. Bolton told reporters, “is the president wants a real deal.”

He rejected the suggestion that the United States could not be trusted to keep its agreements when political winds change. “Any nation reserves the right to correct a past mistake,” Mr. Bolton said, citing President George W. Bush’s decision to withdraw from the Antiballistic Missile Treaty in 2001.

The Trump administration, he said, would continue to work with Europeans to pressure the Iranians. He dismissed those who said the United States was on a path to war with Iran, though he did not present any new diplomatic initiatives. Another senior administration official acknowledged that there was no Plan B.
