NEW YORK — While President Donald Trump’s decision to withdraw from the 2015 Iran nuclear deal is widely unpopular at the United Nations, which he addressed today, Trump’s top diplomat and national security adviser both got an enthusiastic reception from the private United Against Nuclear Iran (UANI) conference here for the administration’s exit from the deal and focus on maximizing economic pain on Iran.

“The Iran deal was the worst diplomatic debacle in American history,” national security adviser John Bolton told the UANI conference, held at a midtown New York hotel a few blocks from the UN, where the 73rd UN General Assembly high-level week is underway.

“The days of impunity for Tehran and its enablers are over. … Let my message today be clear: We are watching, and we will come after you,” Bolton said in conclusion today, to applause.

Secretary of State Mike Pompeo got a standing ovation when UANI board chair and former Sen. Joseph Lieberman introduced him as a longtime ally in opposition to the 2015 nuclear accord, negotiated by Iran and six world powers, including the past US administration of President Barack Obama.
