Neither Great Britain nor Eu in general can now blackmail Russian authorities. It is more impossible than in case of Soviet Union. Soviet Union was military stronger but it had many vulnerable "friends" in different continents. Its ideology was expansionist and it was impossible to loose even one sphere of influence.
Russia today is defending. Today ideology is not so expansionist. Now it is an ideology of persecuted Nation. For such state it is not dangerous to loose any sphere abroad or even a separatist region within: that only confirmes the thesis of persecution. As to Russia in general it is nor Kosovo or even Iraq it is a strong state nobody can occupy or even isolate.
So the only policy is to propose smth interesting to the upper classes and inevitably to the man in the street. As to proposals. the West in general doesn't have any. The only thing now is to open fronteers because from Russia as from Brasil few people can emigrate (they live only for megapolis within the state). But this process is stopped be British government
Did you hear about the the Russian planes flying into British air space?
Do you really think they lost smth there?
the Russians enjoying life in the UK would dissagree, but hey!
Very few people in Russia are anxious about them
