Gary Samore, President Obama’s former principal advisor on arms control and nuclear proliferation who currently serves as the Director for Research at the Belfer Center, gives his take on the agreement struck between Iran and a group of world powers referred to as the P5+1 to restrict and monitor Iran’s nuclear research and development program. He explains why he supports the pact, what concessions he’s most worried about, why he doesn’t believe Iran will be able to cheat, why Iran’s enhanced economic power won’t destabilize the region, and why United States allies such as Israel and Saudi Arabia should have less reason to worry.
