In Foreign Affairs, Kenneth Waltz, the towering international relations theorist, argues that nuclear balancing will bring stability to the Middle East. He writes:
Most U.S., European, and Israeli commentators and policymakers warn that a nuclear-armed Iran would be the worst possible outcome of the current standoff. In fact, it would probably be the best possible result: the one most likely to restore stability to the Middle East.
Diplomacy between Iran and the major powers should continue, because open lines of communication will make the Western countries feel better able to live with a nuclear Iran. But the current sanctions on Iran can be dropped: they primarily harm ordinary Iranians, with little purpose.
Most important, policymakers and citizens in the Arab world, Europe, Israel, and the United States should take comfort from the fact that history has shown that where nuclear capabilities emerge, so, too, does stability. When it comes to nuclear weapons, now as ever, more may be better.
