War so soon? Ehhh... this will be interesting
Yes. Poland has grown into a real threat since the days of the triple alliance. Talk about being stabbed in the back.
So long as Poland isn't using Siberia as a corridor to pull Ming's troops through to Denmark, you ought to be ok.
Just make sure that Poland is busy with the Turks, otherwise their entire forces will be against you.
Poland is a formidable enemy, but the Scandinavian forces are not weak either.
Poland in Siberia?
Push them into Siberia and keep them there.
Nah, I'd rather keep them as a barrier between me and the Ottomans.
Attacking Poland might lead to weakening them so much that the Ottomans take advantage and grab large parts of the Balkans.
That has already happened. My main concern is for them to expand all the way up to my borders. As is, the Austrians are already having serious problems containing them.
