Too high risk, I'm afraid. Poland's flat geography right in the middle of the North European Plain has no major land barriers. It's wide open to the north, where it faces the Baltic Sea, and the ranges to their borders with the Czechs and Slovaks in the Carpathians and High Tatra have an enormous gap between them that's easily navigable. We'll be caught in the middle of it all if their neighbors decide that it's finally the day to conquer Poland.
