The success or failure of such a strategy, will ultimately depend on BTC-e's ability to convince people of it's long term viability.
First an foremost is the placement of their servers out of FBI reach so they don't get shutdown again. This is not as easy as it sounds, but it it not impossible either. There are many countries that wouldn't let the FBI do anything on their soil. If BTC-e can convince me that their servers are safe, I would give them the benefit of the doubt and trade on them again.
And there my believes also kick in. If you compare the Russian user base to the Westerners it seems that the Westerners are the minority here and the Russians react very differently to USA threats than Westerners. So, my best guess is, that the btce is offering some withdrawal/deposit in RUR, relaxing the KYC for Russians and they will flow back to the exchange.
About the servers, yeah, you are right. There are many jurisdictions where the USA can't steal anything. It is also very easy to setup reverse proxy and route ssl secured traffic through multiple locations. The domain should be .su just for the reenactment fun of cold war.
