In July 2015, the five permanent members of the UN Security Council, Germany, and the European Union -- concerned that Iran's uranium enrichment program, used for peaceful purposes, might be diverted to the development of the Bomb -- worked out an international agreement with Iran blocking that possibility. The agreement granted Iran sanctions relief in exchange for significant, enforceable restrictions on its nuclear program. But, from the start, Republicans opposed it and, when Trump became President, he quickly sabotaged it.
