Video: Iran President Hassan Rouhani: no nation should possess nuclear weapons The speech by Hassan Rouhani came hours before a meeting that will mark the highest-level direct contact in six years between the United States and Iran over Tehran's disputed nuclear activities. "Almost four decades of international efforts to establish a nuclear weapon-free zone in the Middle East have regrettably failed," Rouhani told a United Nations meeting on nuclear disarmament on the sidelines of the General Assembly. He was speaking on behalf of the Nonaligned Movement, which represents dozens of mostly developing countries. Israel is the only Mideast nation that has not signed the landmark 1979 Nuclear Non-Proliferation Treaty, and Rouhani said that has prevented the region from establishing a nuclear-free zone. "No nation should possess nuclear weapons, since there are no right hands for these wrong weapons," Rouhani said.
