Preserving the Iran Nuclear Deal

Controversy has surrounded the Iran nuclear deal since it was signed two years ago. Although the main stipulations of the agreement have been successfully implemented—Iran has so far complied with the restrictions on its nuclear program in return for the lifting of economic sanctions—the agreement continues to generate harsh criticism in both Iran and the United States.The promise of the deal includes not only rolling back Iran's nuclear capabilities for the foreseeable future but also paving the way toward a more constructive diplomatic relationship between Washington and Tehran. Its survival, however, depends on complex and turbulent domestic politics in both countries.Since he started his bid for office, President Donald Trump has been a forceful detractor of the agreement, repeatedly vowing to dismantle it. Today, his administration is conducting a review of its Iran policy, of which the nuclear deal is a critical component. He has already indicated that he wants to increase pressure on Iran, and his administration has upped the ante with the Islamic Republic, including by suggesting that America is looking to support elements pursuing a transition of power in that country.But the nuclear deal affords the United States a number of opportunities, if the administration sustains it. The United States should clearly reaffirm its commitment to the deal; help reintegrate Iran into the international economy; keep official channels of communication open with Tehran; and engage, rather than isolate, the Islamic Republic
