@Stephanie, when the fuck did anyone in Europe was shot down by a drone? Stephanie, you are not pragmatic, you are absolutely detached from the real world. Do you want to tell me that democracy like the one you exercise in the Netherlands, were gays can marry and you can vote for whoever you want is somehow worse than Russian dictatorship (and by the way, they had their share of stealing from the world, so by your logic democracy should work great for them). And I don't advocate the whole world should live by our standards, I certainly believe that many conflicts in the world like Rwanda or Pakistan/India is exactly because after colonial times Europe thought that everyone can leave in the same form of state as we do, but they were wrong. Iraq wasn't messed up because they didn't have democracy, it was messed up because they used to kill whole Kurdish villages with gas attacks.
Ukraine however is a developed, European country that for centuries (or at least century) has been struggling for freedom and democracy, and you don't think that's worth fighting for? Sad.
As for Crimea, first of all that is an entirely different case than Donbas. Crimea was for a long time Russia (not USSR but actual Russia) and was given under Ukrainian administration as a gift in times were people thought USSR is everlasting. The vast majority was Russian and the Russian invasion was conducted in such quick fashion that there were almost no losses on either side. While in my opinion still is a rogue action, to just change borders just like that - that could be somehow rationalized and justified. Even so, Tatar population which is the native population of Crimea now faces great repercussions under Russian rule, with political leaders being imprisoned and their parliament disbanded. What you see in Donbas however is a long lasting conflict that has taken over 10,000 lives and costed tens of billions of dollars in losses. People has to actually take your advice, fleeing the region, leaving their homes, possessions, often members of family that weren't able to come, now living in refuge camps like the ones we have in Poland. But sure, next time I meet a Ukrainian I'll tell them to just stop fighting and accept Russian rule.
