From RIA-Novosti. The chief of Russia's General Staff said Monday he could neither confirm nor deny reports that Ukraine had sold 250 nuclear warheads to Iran. "Russia's General Staff has no information about whether Ukraine has given 250 nuclear warheads to Iran or not," General Yury Baluyevsky, also deputy defense minister, said in response to an article in Novaya Gazeta newspaper Monday. "I do not comment on unsubstantiated reports." The newspaper said that Ukraine had failed to return 250 warheads to Russia in the 1990s when the former Soviet republic declared itself a nuclear-free zone. The paper suggested the warheads could have been sold to a third country, including Iran. "Russian military stalls on reports Ukraine sold warheads to Iran" 3 April 2006 http://en.rian.ru/russia/20060403/45107320.html I find the implication of this report hard to believe; the Ukraine couldn't be certain what the new owner would do with these weapons. The Ukraine could not be sure such weapons would not cause it grief outweighing the benefit of the purchase price. Also, I've read elsewhere that atomic fission detonations have a distinctive radioactive signature and that its possible to determine where the uranium on an atomic bomb came from by analyzing fission debris. A bunch of atom bombs going off that, in effect, said "Made in the Ukraine" might be tough to explain. I'm skeptical whether any of the constituents of the former USSR would dare to turn such devices loose on the international market. It's not the same thing as selling off excess AK-47s or tanks. All the same, I can't really prove that this report isn't true either.
