They deny that, but of course you know for sure that they are lying, that the nukes went missing, and you have the proof. Just like I know for a fact that there are alien craft hidden in Area 51.
It was a statement made by General Aleksandr Lebed, former Secretary of the Russian National Security Council, in a meeting with an American congressional delegation.
Perhaps he was drunk, or lying, or just plain unable to find the people who knew which cupboard the devices were safely locked in. But he did make those claims. And you are missing the wood for the trees.
This "wood" (and the US report) consists of exactly one person who made this claim, and a member of corrupt Yeltsin's entourage to boot. I'd say if these nukes were real, they would have exploded somewhere by now.
Try harder.
