Okay, I misremembered, but it was implied at the least - unless you meant to claim that Russia was the only country where public opinion mattered.
Knit, yes, I did know about the infamous influence of vodka upon Russian demographics, and I sadly have to inform you that according to that article illegal (and thus, for the most part, unhealthy/toxic) alcohol is on the rise.
On the rest: The USA stuff may very well be, but it would've remained purely diplomatic. Nobody would've started sanctions like we've seen.
And, honest question: Was the USSR sanctioned because of Afghanistan?
Yes! It was put under a rather heavy embargo, which continued the list of the various sanctions it was subjected to during the Cold War.
And here's another thing. Let's assume a hypothetical model of sorts: Russia, ruled by Navalny, is a furiously pro-European state, a member of both EU and NATO and a faithful ally of Washington is all metters political and economical. And then this freedom-radiating behemoth does the same thing in Crimea, formally a part on now furiously anti-NATO Red Maidan Ukraine, that Putin's Russia did. Would it get the same treatment? Of would it's actions be excused in official rhetoric and propaganda both? Would attention be drawn on how much Crimeans want to be a part of Russia? How bad and scary the new Kyiv is? How Crimea is similar to Kosovo, and thus it's reunification with Russia follows up on an established precedent? I disagree with you that if Putin had a free and fair referendum in Crimea, the Washington wouldn't sanction it. No, it would sanction it on pretty much the same basis as before - the referendum was unconstitutional (and it technically would be, it's impossible for a part of Unkraine to secede without the approval of Kyiv's Rada), the results were falsified, it is an affront to European peace, all because the supposed illegality of the referendum is just an excuse, the real problem is that Russia is no longer docile and appears to openly confront the spread of NATO. And don't even get me started on the rebels.
Edited an obvious factual mistake, made due to momentary stupidity.
EDITEDIT: Illegal alcohol is, and has been, always present in Russia. It's not even that bad, when made by and experienced brewer.
