Definitely a time where everyone was clambering for power over the graves of dead giants.

Poland and Soviet Russia were both climbing out from the ashes of monarch rule. They quickly scrambled to reclaim borders and expand those borders. Poland was technically the first to expand and move into Russian territory by capturing Vilnius and then Kyiv. This was not a “big bad Russians were conquering poor Poland” situation.

Poland was not the victim you’re painting them to be in this scenario.
