‘Treasure’ of a different sort turned up in one bunker in 2004. Some 16 tons of mustard gas canisters were found in a bunker only 40km from Tirana – the US had to pay the Albanian government some $20m to safely dispose of the weapons.
No doubt USA used corruption in the 90's to buy Russian secrets or weapons. General "Dimitri" takes suitcase full of cash and screw the glorious motherland.
Strictly speaking, the US did not have to pay. They chose to pay as they preferred that to the alternative: unsecured chemical weapons sitting around waiting for anyone to take them.
