Well if you are going to argue that other examples are not quite like Gaza so they don't work, then I'll argue that you can't make the move of "there is no other country that under the same circumstances wouldn't behave in the same way", because philosophically speaking, the only country who could ever be "that analogous" would be Israel itself and nothing else entirely, so the counterfactual just doesn't work.
You say that we in the west are not well informed about palestinian's actual drives because while we think it's the rockets and the killings which are making the people support Hamas, it's actually their own particular racist hatred towards Israel. My problem with this whole argument is that it is not only borderline racist (almost saying things like "These palestinians are just hateful people"), it's that it misses the whole point of the very "racist" concept at all. People are always racist when they perceive the Other as a Problem. This "Problem" may well be manufactured (like the "Jew Problem" in nazi Germany), or it could be due to a real issue (like the pervasive racism of english people towards the germans post-war). Thing is, that even if this is a case where this "Problem" is a manufactured one through islamofascist propaganda against the "Jews" and so on, the worst thing the Israel government can ever do is to prove them right and empirically confirm to them the things they are brainwashed in, that these are people who will kill children, who will endlessly oppress palestinians, etc.
However, I don't think this is without "issue". The fact that this territory is de facto controlled by Israel, blockaded, sieged, and has engaged in what looks like straight out of the gut cowboy revenge does indeed transcend this "Problem" from an ideological brainwashing towards something more.
The only possible route for Israel to get out of this quagmire is to utterly destroy this image they have on the palestinian heads. It is possible that this could happen "on its own", with the big majority of Gaza pop saying "enough is enough" and end Hamas, etc., but I don't bet on this.
