If you think about moving to Slavic World, consider Montenegro, my friend in Kotor is renting his house to some Norwegians for years. There is a fjord-like bay, food is good, prices are low (1.000 Euro per month to be a king), the sun is shining and the temperature is always above the zero.
Why would someone want to move from Norway? That is, I have never been there, but from a distance I have always considered it to be paradise.
And in Sarajevo, Muslim Arabs are spending millions spreading salafist Islam!
No thanks!
Poland is much safer!
They do in recent years, but the Bosnians are very liberal people. Some of them are open atheists, others eat pork, basically, only old women cover the head (Balkan thing, due to the bad hair mostly), and a few would reject alcohol (if they are ill or so...). After the war some of them turned to more extreme versions, but generally speaking, they could be considered as the true Europeans.
