When American diplomats sat down for the first in a series of face-to-face talks with their Iranian counterparts last October in Geneva, few would have predicted that what began as a negotiation over Tehran’s nuclear programs would wind up in a stunning demand by the Security Council that Israel give up its atomic weapons.

Yet that’s just what the U.N. body did this morning, in a resolution that was as striking for the way member states voted as it was for its substance. All 10 nonpermanent members voted for the resolution, along with permanent members Russia, China and the United Kingdom. France and the United States abstained. By U.N. rules, that means the resolution passes…

The resolution calls for a nuclear weapons-free zone in the Middle East. It also demands that Israel sign the 1970 Nuclear Nonproliferation Treaty and submit its nuclear facilities to international inspection. Two similar, albeit nonbinding, resolutions were approved last September by the International Atomic Energy Agency in Vienna.
