Why surrender and let the invader murder with impunity, when you can still make him fight for every inch.

thats where we're at. Thats been the score since Bucha. Because Ukraine resisted, both sides hate each other like Israel and Palestine now. every time Russia gets into a city, they rape and pillage, murder civilians on the street, torture and castrate POWs before murdering them, and flatten cities to the ground.

you dont surrender to that. you fight to the death. you have no choice.
