As Ukrainian, I don't remember launching missiles on russia, or, in fact, any aggression towards russia. In its turn russia did recognize borders with Ukraine in multiple treaties, and on top of that security guarantees promised in exchange of 3rd by the size world nuclear arsenal.
Just a quick reminder, that Iranian and Hamas policy towards Israel is extermination. Palestine was never recognized by Israel or USA. Israel is not recognized by Iran.
So tell me, what parallels do you see between these conflicts? Human misery and destruction is hardly a common ground, and even in that, scale is incomparable.
