So, in your view, the communists were at least a bench of traitors and USSR was the ultimate enemy BUT they should have helped the Nationalist Polish to fight the Germans. The ones who when in power put them in jail when they could…

Sorry Brenus but you are not listenting or don't want to listen.
You are mixind nationalism and patriotism.
Every citizen of Poland, no matter if he likes government or not, is obligated to defend country.
Especially when enemy is sending people to death camps. If citizen does nothing - he is traitor.
Country Army were not polish nationalists - they were polish patriots. Many of them did not agree with
government before ww2 but they were fighting with common enemy.
