There is absolutely no doubt that the ongoing political mess in Ukraine affects Europe adversely. But it seems like it’s still not even a half.
Residents of Eastern Ukraine are fleeing from war. Statistics says that in 2015 the influx of refugees from Ukraine to Europe has increased tenfold! Ukrainians leave their homes for Germany, the Czech Republic, Spain, Italy, Lithuania, and Estonia. Recent events in the city of Mukacheve made residents of Western Ukraine, and especially of Zakarpattia province, where the most part of population contain ethnic Poles, Hungarians and Romanians, to start running from the country as well - running from tyranny and violence of Ukrainian nationalists.
However refugees - is not the main problem for Europe. It is an open secret that Europe strongly supports the actions of Poroshenko in Eastern Ukraine, and evidently still keeps hopes for a speedy resolution of the situation alive. Meanwhile the recent armed conflict with the Right Sector obviously weakens position of Kiev in Donbass. First of all because Kiev now has to withdraw some troops from East and send them to the Carpathian, and secondly because Right Sector in its turn derives its battalions from Donbass as well.
