This WSJ editorial says president Trump can exit because president Obama never really built support for the Iran Nuclear Agreement of 2015. Stephens in the NYT cites a Pew poll at that time showing only 21% supported it with 49% not supporting it.  This editorial says the deal made by Obama gave Iran $100 billion of sanctions relief and a chance to revive its nuclear weapons program after a 15 year waiting period. It says this increased conflicts and wars in the Middle East. President Trump said in his announcement on May 8, 2018 that the deal never led to "peace, or calm and never will."

Another issue of winning popular support is mentioned, as WSJ says president Obama did not submit it as a treaty to the Senate for approval. The Trump administration has its own work now to build support with Europe in fixing the nuclear deal's weaknesses, and winning support from Democrats as well as Republicans for sanctions and new negotiations that help bring a better more peaceful Middle East, so that Iran can focus on lifting living standards and improving the economy, setting a new course.
