What if Iran already has a bomb, or bombs? Military expert Richard Maybury has suggested that several countries may have nuclear weapons that we don’t know about. There are gaps in records tracking the Soviet Union’s bombs when it dissolved. Some of those bombs may have become available on the black market, where they would have undoubtedly commanded sky-high prices. North Korea or Pakistan, both nuclear powers, might sell bombs at the right price, especially if that price including substantial “commissions” to key officials.

At first blush it may appear farfetched, but even Russia or China could sell bombs to Iran. They are chafing at the US’s unipolar view of the world. Iran would use the bomb under only extreme circumstances, and the Russians or Chinese would undoubtedly extract assurances that an Iranian bomb, if detonated, would blow up in London, Washington, or New York, not Moscow or Beijing. The threat would be clear: a detonation in Russia or China would mean the complete destruction of Iran.

Those who dismisses the Iranian agreement with the argument that Iran will eventually breach it should ponder this question: why would Iran go to all the trouble and expense of secretly developing a nuclear bomb, risking detection and war, if they could simply buy bombs, and, better yet, keep them secret? It would be naive to assert that a black market in nuclear arms is impossible. If Iran were a buyer, the detection risk would be minimal: bombs could be put in ostensibly commercial aircraft, flown from Moscow, Beijing, Pyongyang, or Karachi to Tehran, from which they would be transported to and hidden away in some remote, deeply fortified bunker. The Iranians might not have much, if any, launch capability, but they could surely smuggle bombs into the US or Europe for either nuclear blackmail or outright detonation.
