MOSCOW (AP) — The doomsday scenario of Soviet nukes falling into the hands of rogue states or terrorists has, as far as is known, remained fiction, thanks to a massive U.S.-Russian effort to lock the weaponry up safely after the Soviet Union fell apart.The vast nuclear arsenal, scattered among several newly independent nations, was secured because Russian military officers acted with professionalism and honesty, Moscow and Washington shared clear priorities, and the U.S. taxpayer coughed up billions of dollars, former top officials who dealt with the Soviet nuclear legacy say.
This seems a bit simplistic in it's thinking...

"If somebody or a terrorist group got hold of a nuclear weapon, they would probably use it as quickly as possible," said Steven Pifer, who served as U.S. ambassador to Ukraine, held other senior State Department posts and is now director of the Brookings Institution's Arms Control Initiative. "So the fact that you haven't seen a nuclear detonation ... reflects the fact that the nuclear weapons have been maintained in a secure way."
