I've never heard of anyone failing kindergarten before, this is a first.I’ll explain like we are in kindergarten.
Ukraine has a territorial dispute with Russia. Ukrainian army is not an existential threat for Russia.
Ukraine does not claim that Russia is not a legit country.
israel is dealing with enemies that want it completely dismantled and overrun from river to sea.
it is not a territorial dispute.
Russia wants to invade and take all of Ukraine, they are now occupying about 1/4 of it.
Israel wants all of Palestine, they are now occupying all of it.
Palestine has a territorial dispute with Israel. Palestine has no army and is not an existential threat to Israel.
Israel refuses to admit that Palestine is a legit country.
Its amazing that you can even think your comparison has any merit.
