Speaking on CNBC, Carnegie’s Karim Sadjadpour discussed the potential fallout if U.S. President Donald Trump pulls out of the Iran nuclear deal. Sadjadpour argued that Trump’s doctrine aims to simply oppose former U.S. President Barack Obama’s foreign policy, and the Iran deal is one of Obama’s signature foreign policy legacies. He further stated that Trump is not only acting in contrast to almost all of U.S. allies in the world, with exception of Israel, but also the national security brain trust.
