i'm sure Russian services have most important things to works ... and just for info (from wikipedia) :
In the 1980s, the glasnost liberalisation of Soviet society provoked KGB Chairman Vladimir Kryuchkov (1988–91) to lead the August 1991 Soviet coup d'état attempt to depose President Mikhail Gorbachev. The thwarted coup d'état ended the KGB on 6 November 1991. The KGB's main successors are the FSB (Federal Security Service of the Russian Federation) and the SVR (Foreign Intelligence Service).
