NATO expansion towards east is a problem and only adds fuel to the fire. "NATO overplayed its hand" is an understatement, it's a long-term strategy. Also, this has nothing to do with propelling democracy to ex-Soviet (or other) states but with geostrategic games between two nuclear powers. USA & NATO have no problem with authoritarian regimes provided they are willing to fully cooperate with them. There are dozens of examples from the past and today. That's why I'm always suspicious of the so called orange revolutions, certain foreign funding NGOs etc. There were attempts in Belarus and Kazakhstan lately as well. Is it a coincidence, I don't think so. If, one day, Ukraine joins NATO, it would only be a matter of time before NATO tactical weapons are installed near Ukraine-Russian border. That means the missiles could hypothetically reach Moscow within 5-10 minutes. What would you do if you were in Putin's position... His support for Venezuela regime is a moot example and nowhere near the problem of the same magnitude for Americans as the Ukraine is for Russia. If it was closer to the US border (like Mexico for example) than fair enough. And we all know how USA reacted to Cuban missile crisis.
