Polish national strategy pivots around a single, existential issue: how to preserve its national identity and independence. Located on the oft-invaded North European Plain, Poland's existence is heavily susceptible to the moves of major Eurasian powers. Therefore, Polish history has been erratic, with Poland moving from independence -- even regional dominance -- to simply disappearing from the map, surviving only in language and memory before emerging once again.
For some countries, geopolitics is a marginal issue. Win or lose, life goes on. But for Poland, geopolitics is an existential issue; losing begets national catastrophe. Therefore, Poland's national strategy inevitably is designed with an underlying sense of fear and desperation. Nothing in Polish history would indicate that disaster is impossible.
To begin thinking about Poland's strategy, we must consider that in the 17th century, Poland, aligned with Lithuania, was one of the major European powers. It stretched from the Baltic Sea almost to the Black Sea, from western Ukraine into the Germanic regions. By 1795, it had ceased to exist as an independent country, divided among three emerging powers: Prussia, Russia and Austria.
