e: The EU collapses and national egoism returns into the European political agenda. Every man for himself, is the new motto! A new nationalistic government in Poland starts to make territorital claims to Lithuania, Belarus, Ukraine and the Czech Republic.
the thing is such though experiment is useless because no matter what happens with the EU no sane Polish government would do that - and sentiment for old borders is much greater in Germany than in Poland - there is NOT A SINGLE organization in Poland that promotes getting back some territory in the east - even the most nationalistic organization - that there are some misguided individuals who happen to spam forums about it is just the bundle transaction of the freedom of speech on the Internet
you were big and important before the First and the Second World War - I think it was pretty costly to seek to prove your strength and importance to world - does Germany's strenght and importance allow her to make everything in Europe to suit her????
