Reading “The Iran nuclear deal, one year later” [news, July 14], it’s difficult to reconcile David Albright’s assessment that “the deal has been a real success in getting deep reductions in Iran’s nuclear capability” with something not included in the article: the assurance the “moderate” Iranian president, Hassan Rouhani, gave his ministers this month that Tehran could quickly restart uranium enrichment.

Even Mr. Albright, a nuclear expert with the Institute for Science and International Security, acknowledged “we don’t know what we don’t know.”

What we do know is that we can’t trust the leaders of Iran, and we need to be very skeptical.
