That's why I think their is a fundamental difference in how the conflict is viewed
Western leftists view it as a white european colonial project vs. the arabic world
in the islamic world, it's viewed as a jewish vs. muslim battle
When you say "Western leftists" you need to be more specific, because prominent leftists don't frame the argument in this manner whatsoever. You've already conceded this point by stating that you agree with Chomsky's stance. What are your thoughts on Finkelstein? Discussions surrounding the inception of the state and discussions surrounding the way Palestinians are treated are separate issues.
Hamas doesn't want peace though, how do you negotiate for peace when one (or perhaps both) have no interest in it?
This is just an reductive argument that you're attempting to put forward. "Hamas don't want peace and therefore Israel have no choice but to protect themeselves from this terrorist organisation." That is in essense what you're trying to say here, correct?
