According to a recent survey, there is widespread opposition to Iran obtaining nuclear weapons. And in most countries, there is majority support among opponents of a nuclear-armed Iran for international economic sanctions to try to stop Tehran's weapons program. The Chinese and the Russians are notable dissenters in this regard. The poll also found majorities in Western Europe and the United States disposed to taking military action to prevent a nuclear-armed Iran. Again, the Russians and Chinese disagreed.
