A few months ago I went to a talk by Vladimir Kara-Murza, a Russian opposition leader. One thing that really struck me was when he pointed out that something like the last 6 regime changes in Russia (except maybe one) happened in periods lasting only 3 days. So you woke up on a Monday to the current regime, and by Thursday that regime was history and a new one was in power. I keep hoping to see this hold true again sometime soon.
