As a Libertarian I hate Putin. I also hate the fact that people seriously care about Crimea. I don't want to defend Putin, but what he does in Russia's sperhe of influence isn't a serious threat unless he invades a NATO country.
And if the West does nothing about Crimea he will invade a NATO country with probability 1. Estonia, Latvia, Lithuania, Poland, etc. are both in Nato - and in what Putin perceives as Russia's sphere of influence.
First off, how the f*** would a region which democratically decided to join Russia somehow lead to Putin going batsh** and invading someone?
Agree with the point you're trying to make, but there is no way anyone can call what happened in Crimea democratic.
