If we are to remain honest, we should accept the fact that the US is effectively controlling the monetary and, more broadly, financial flows around the world (at least, the better part of them). At a time, the train of events got close to cutting Russia itself from the SWIFT international payment system. Right now Russia tries to get itself out of these ties and break away with the payment systems controlled by Uncle Sam. In fact, it is not about using Btc-e again if (when) it restarts (most people will be happy to use it again anyway) but rather how useful it will ever be. As I see it, they could only restart (in any meaningful way) as a cryptocurrency only exchange with no fiat deposits and withdrawals (like Bitfinex had been cut off of the fiat transfer channels in April)
