I'm wondering if Putin and Bush had a little talk about this in Texas. It would be typical of Bush. Clinton was diligent in cleaning up paper trails but Putin doesn't labor under the restrictions Ashcroft does.
The Bolsheviks stole Russia from the people in 1918. I do not believe Russians will allow the oligarchs to keep what they stole in the 1990s.
Interesting enough, from 1920 on, the Bolsheviks fenced their swag in New York City. In the 1990s, the oligarchs laundered their loot in New York City.
