The support of 42 senators is a meaningful development for the White House and a positive step toward resolving the nuclear issue. It was achieved due to the work of an administration committed to a peaceful resolution to the issue as well as the efforts of many groups, including the AIC, supporting the agreement. Nevertheless, all of the Senate Republicans, a few Senate Democrats, and all of the Republican presidential candidates have expressed their rejection of the deal, dubbed the Joint Comprehensive Plan of Action (JCPOA). As a result, it is unfortunate that this important foreign policy achievement has become a partisan and controversial issue. Future US administrations could even undo the work that American, Iranian, and other diplomats meticulously achieved over the course of many months. Furthermore, the implementation phase will prove particularly tricky, as a conflict could arise either in terms of sanctions removal or on Iran’s nuclear program.
