Look at your ex-Soviet neighbors - they are running away from you but you're still dreaming your imperial dreams.
Too easy to be true. Firstly that's wrong to assert everybody's running. If you check better there you may find the followers of that crazy idea even in nowadays Poland (in asylum perhaps or wherever) to say nothing about the former USSR countries. Secondly everybody wants to be the boss, not to share the power. Thirdly you (or should I say particularly you) would be dreaming imperial dreams as well, if your country was an Empire by the date of your birth.Too bad it wasn't...
Tiutchev wanted Russia to the Elbe river, those panslavists to Oder only but the general approach has not changed at all, be it Romanoffs, be it Stalin or Putin.
What makes you feel it stays the same? Are there any maps produced of the same kind as you found? Do we attack Poland? It seems like you badly want to be attacked or threatened by Russia or otherwise your mood at least turns bad for that day.
I do not like Russian imperialism and just referring to the map makes a good example of it.
It's 100 years old. What does it have to do with the actual reality?
Only your possibilities are not the same anymore.
There're ups and downs, probably some time later you'll occupy us and create another "Katyn" (which we actually have in plenty but don't cry aloud about them) for us... and there will be Poland (ta-da!!!) making panslavic dreams come true.
