In the early 1970s, I served as a Peace Corps Volunteer in Mahallat, Iran, a small town between Tehran and Esfahan. Today, I belong to the Peace Corps Iran Association, which works to improve relations between our countries. At least 1,500 volunteers served between 1962 and 1976. We have very strong and fond memories of our Iranian friends, colleagues and communities. We saw how deeply Iranians value their history as a nation and a great culture. And we experienced the hospitality for which Iranians are renowned. Peace Corps left Iran before the revolution and ensuing events, but we have held out hope that in time the rift between our countries would be overcome. The nuclear agreement is a monumental step in that direction.
