Medved - I am not saying Russia has anything to do with it.

I don't know whether it has or not, my guess is the Russian state doesn't, but some private Russian citizens and Russian organisations do. I don't believe that the Russian army is there.

However, I live in Western Europe, and I just have to turn on the TV to hear the agitation against "Russia's involvement in Ukraine"

It-ogo who was active here and lived in Donetsk, said that he personally saw Russian Federation soldiers in Ukraine.

It's hard to know what to think and I know for sure that I cannot trust what I read in Swedish or English papers, they are completely biased.

I recognise the rhetoric and agitation when Western media wants to really villify somebody - we see it all the time (Iraq, Libya, North Korea, Syria, Venezuela, Talibans etc).
Right now it's Russia and Putin and it's the culmination of something that's been building up for years. Obviously "somebody" wants the Cold War back.
