I say probably because I have little direct knowledge of what the Soviets are capable of. But I do know that the Soviets have been caught doing some impressively sneaky stuff. One thing that sticks in my mind is the placement of a (completely passive) eavesdropping device in the Oval Office. Said device was unpowered, and missed during a comprehensive check for bugging devices. So I'm making an assumption here: namely, that they have only refined their techniques in the areas of statecraft and espionage.
