Yes, Russia is corrupt. Yes, it lacks (to a degree) freedom of speech, but then again so do many, perhaps even most countries. The world is not Switzerland: this kind of **** is the norm. But I can't agree with the people who see Putin et al as Stalin all over again, and draw a simplistic view with the great, enlightened, progressive free-market path versus the old, evil ways of authoritarianism. There's no use pretending Moscow is Pyongyang. It's not that simple. StratComm had it right: the choice was (around the end of the 90s) between a potentially bad government and no government, and I think the right choice was made. But then again, it's not like Russia has a proud tradition of democracy: they just fell back into familiar patterns
As for Chechnya, yes it sucks for them. When or if Russia pulls out, Chechnya as a nation will have ceased to exist and it's population will have been decimated. It already is. Iraq is nothing compared to Chechnya, that much is clear. But again, half the world is engaged is some sort of civil war, insurgency or conflict. It's not exactly a unique situation.
Specifically regarding the recent gas row with Ukraine, I think it was perfectly reasonable to expect a independent nation to pay market price for gas. If Ukraine wants to go it's own way (or rather, not it's own way but the EU way, but whatever) that;s fine. But don't expect the subsidies to continue. Every other European nation paid a certain price, and Ukraine was paying five times less.
