I see more Israel/Ukraine flag combos, but I have seen a few of those as well.

I sorta get it, if someone were looking at both situations purely as "resistance fighters against their oppressors" They aren't actually comparable in that way at all, but the mental gymnastics required for somebody with only a surface level understanding isn't too great. I feel those might be the people that you could have some hope of educating on the realities of the situation.

They turned around pretty fast to be pro Israel.... I bet.

I can see how someone could believe something about both of them being underdogs who are bullied by their big scary neighbours.

I would. Everything exists in this crazy world.
