I get that there is lot more nuances than russo-ukrainian, but imo there is a lot more similarities than you seem to imply : both Russia and Israel claimed that the land belonged to them before, that they should get it back, and use violence to kill local people who tried to resist or move them. The only difference is that Israel did it with the help of western countries and partially according to their laws, so they get like an aura of legitimity, but the acts remains quite close.

I do not like when people basically do not accept violent behavior but accepts them when they are allowed by some law or authority.

(Also yes Hamas is doing bad things and should be held accountable in some way, just like Ukraine to my eyes. But still, for me it remains obvious who kills more, who steals more, who oppresses more)
