What is the future of Kaliningrad Oblast will it remain a exclave of Russia returned to Germany,annex by either Lithuania or Poland or became a independent country which is most likely.
I'm afraid I can't put forward my prediction about the future of "oblast" but the option "became an independent country" I would place in the bottom of the list without a moment's hesitation.
That act of protest against another putin's fosterling (Boos) - pl.wikipedia.org/wiki/Gieorgij_Boos
and putin's power in general is quite often thing in today's Russia. I may take part in such a protest, however that doesn't automatically mean I want Moscow to be an independent country.
As for linking to SF... I wouldn't consider that source reliable enough to take into account. Besides, opinion of extreme leftists/rightists doesn't reflect the one of society on the whole.
