It is a cheap argument. I made it to point out your bias on this issue. It's the Arabs responsiblity to NOT act irrationally, even though the side your supporting IS acting irrationally? Is it "good" irrationality though? Do you have this idea about Israeli cultural that it isn't massively racist and that its government deploys a police state? All able to be done because of Western backing?
Your last statement kind of ends this discussion. As you live in a world where the Israeli Government wants "peace and cooperation", not conquest. Which the opposite of what they say and lay out in their policy papers. I mean, AIPAC's push for the Iraq War was of course about "peace and cooperation", not an agreement on water rights in Iraq. The paper "A Clean Break" wasn't written. Laying out plans to destabilize the region and make life unbearable for the Palestinians. These things didn't happen in your world.
Instead, Israel was just trying to create a country in a unpopulated place, and all these racists just hate them for it. Israel can't carry out war crimes, it's defending itself from crazy Muslims.
