VIENNA (Dispatches) -- A senior Russian diplomat said on Monday opponents of a 2015 nuclear deal signed between Iran and major world powers are seeking to "undermine the confidence and cooperation” between Tehran and the International Atomic Energy Agency (IAEA). Russia’s Permanent Representative to International Organizations in Vienna Mikhail Ulyanov said the nuclear deal -- officially known as the Joint Comprehensive Plan of Action (JCPOA) -- aims to "restore confidence in exclusively peaceful nature” of Iran’s nuclear program. "The deal fulfills this task. No sign of military dimension was found,” he tweeted.
