I don’t think Berezovsky is telling Putin anything he didn’t already know.
Regretably the Russians, like the French, seem to be incapable of changing governments without a revolution.
Putin is driving Russia straight into the ground. But it seems unlikely that anything can easily be done to fix the situation.
Russia tried to reform itself in the last days of the Tsars, but then Lenin stepped in. That has always been the Russian way, seemingly.
