To say that global nuclear politics is in flux is an understatement. President Trump has announced that the U.S. is withdrawing from the Iran nuclear deal. Meanwhile, he is planning a summit with North Korea in June. Scientific collaboration and cooperation has played an important part in nuclear diplomacy between the U.S. and Russia for decades, and could be a tool in our shifting relationships with Iran and North Korea.
