Obviously, to gain international attention. If they stick to purely a russian domain, it would severely limit their reach as many people (non Russians) would likely avoid this exchange. On the other hand, while a lot of their customers aren't Russian, I do find it frustrating and weird that they mostly release important statements purely in Russian, and not in English. I know that English isn't their main language, but it's extremely amateurish if you haven't even hired people with the ability to communicate in fluent English.

Didn't you know? US of A is the ruler of the world, where their law applies to all countries in the world. If you fart in Uganda, they will have you arrested within 24 hours (if not sooner). It's beyond insane, I know, but that's how they operate. That being said, it's not that BTC-E is completely free here. If BTC-E was indeed used to store and launder the MtGox coins, there is not much that you can blame the authorities for. It's just a rubbish situation that the fair and square traders are the real losers here.
