The reason nothing can be done about this is because Poroshenko is staging a conflict and the EU knows it can't push Russia any further or that will mean war in Europe.
Poroshenko destroyed the International Monetary Fund in Ukraine and now wants an EU membership because the EU is aligned with IMF and that is what the IMF told him to do. He's already a greedy billionaire and will do whatever the EU and IMF tells him to so he can retire even fatter on his palatial estate. The EU has its own plans though and will use Ukraine as a Semitic Muslim dumping ground. Pressure is on Russia to back off so EU can do what they will with Ukraine. Russia is doing the right thing and the whole world a favor by annexing what they can in that region. Russia is really the last anti-Islam stronghold and that will quickly end if they do not put their foot down with the EU. Nobody likes to say it but many from all over the world will tell you how big of a mistake it was to let Islam into their country. It's a horrid religion and belongs exactly where it is. Never mind the people. People can change and be who they want but if it's Islam they want, then they should not be let in. This is why people should have to prove they are acclimating to their host country as is the requirement in Switzerland. Immigration should be much more selective to prevent mass immigration so that the individual can be kicked out if they fail to adapt over the course of several years.
There is much more to this than Putin and for anyone to sympathize with the pig Porkoshenko is horrifying. You don't have to like Putin to be reasonable here and realize that Ukraine is better of with him than they are with the EU and IMF. Christianity had its horrors of course but Europe tamed it and turned into something decidedly better than Islam. Never mind the gay this or that. You can have Christianity and gay rights. Something Russia will eventually sort out but it doesn't mean we should destroy a whole region with Islam because of something we don't agree with right now.
Yes I may be a nut and I'll take my downvotes or messages filled with vitriol but don't think some governments aren't currently deconstructing cultures across the globe for their own means. You do this by quickly injecting millions of refugees who then take over the area and ruin all societal bonds with their extremist views. Think of how even more divided we are now because of terrorism, how untrustworthy the common law abiding citizen has become. This is all thanks to Islam and political figures who use it for their own personal gains. It's really not so crazy if you think about it. Something similar happened with Christinaity too. It was also used as a means for control. Islam is no different.
