The parts where the heaviest protests take place correlate with the pre-WW II Polish borders: http://en.wikipedia.org/wiki/Curzon_Line Being from Poland I wish our politicians tried to use this situation as an opportunity to re-annex western part of Ukraine. Maybe not entire half of it, but f.eg. Lvov used to be a beautiful Polish city before the war.
... and an Austrian city long before that
