This was kind of envitable.
Lets face facts, Poland was partitioned by Russia, Germany and Austria, The russians were cruel masters during this period of time. Then when they got their independence back after a century of darkness (from their perspective) The Russian communist army invaded fucking again. And once again tried to take away their freedom (They won.)
Then the Russians allied with the fucking Nazi's to partition the country yet again and the only reason they fought the germans was because the nazi's backstabbed them. In the aftermath of this the Russians captured Polish patriots and tortured them to death in gulags, their army also raped and committed war crimes on the path to going after germany.
Once the war was over they turned the country into a brutal puppet state and treated poland like a colony. This was pretty god awful for them. Then finally the Russians leave because they mismanaged themselves into semi oblivion. The poles then Joined nato and the EU sacerficing economic prosperity in exchange for the promise that that shit would never happen again.
There was pretty much no fucking way those monuments were staying up, were talking centuries of bad blood here the moment they thought they could realistically get away with it those monuments were going down. And most countries would do the same thing if they were put in the same situation.
