The current antics of North Korea and Iran are simply the latest developments in a process that has been unfolding inexorably since the first nuclear bomb was detonated in the New Mexico desert in July 1945. For about four years, the United States was the only nation able to produce such supremely deadly weapons. Then the Soviet Union succeeded in doing so, followed quickly by Britain, France and Israel. Much later India followed suit, and soon thereafter its great rival, Pakistan.
In recent years, a number of medium-sized nations have shown an interest in acquiring such weapons. Quite a few have developed the nuclear technology to generate electric power for their economies, but that, of course, is a very different thing. Acquiring such nuclear capability requires far less skill and investment than constructing nuclear weapons.
But it has been obvious from the start that sooner or later various nations would elect to go that dangerous route unless steps were taken to prevent them. That was the purpose of the Nuclear Non-Proliferation Treaty, which the United States and the other great powers managed to persuade many nations to sign. But the temptation remained, and the long-dreaded moment has at last arrived when the world is confronted with at least two countries -- North Korea and Iran -- that show every sign of intending to "go nuclear," whether the rest of the world likes it or not.
For better or worse, this has occurred when the United States is the world's only superpower, and thus cannot avoid making the necessary decision: Shall they be permitted to do so or not? Diplomatic pressures, involving both carrots and sticks, are of course being used by many nations to try to dissuade them, but if these fail (and this seems all too likely), the only remaining recourse will be to use military force, and the only country that could conceivably do that is the United States.
