Respectfully disagree. I'm in favor of Palestine engaging in violent resistance, but if you're going to start making apologisms for violence against teenagers you've lost the plot. By way of analogy let's think about the carceral state trying children as adults. It's a barbaric application of state power and violence against someone who's brain isn't even fully formed yet. Add to it the material disparity in power a juvenile has compared to an adult, and it becomes even more grotesque to justify violence against them or flatten culpability that way.

Yes blame their parents to some degree, and very much so the people in power in the Settler-Colonial apartheid state that is Israel, but a just solution isn't one where ethnic cleansing occurs and anyone of Jewish decent, regardless of age or culpability, is killed or forced out of the territory. It's a one state solution that's not a religiously based ethno-natiolist project, but instead a pluralistic project that reconciles the history of disproportionate violence by Israel against Palestinians via restitution/reparations but still takes into account the current material reality.

I'm not even saying Palestine is obligated to avoid collateral casualties (obviously if it can be avoided, do, but don't give up an existential fight and lose it because some might occur) -they're engaged in a justified war of self defense. There will be foreseeable but unintended casualties as is the reality of war in a sense urban area. But I draw a strong line at you legitimizing violence against children outright, and invite you to self-crit.
