> but I imagine the residents of kibbutz be'eri and the 100+ hostages still held in Gaza would disagree that Isreal is fighting for "basically no reason."
On the contrary, I think that those exact people would agree the most. Do you think that they do not wish that Israel did a hostage exchange instead of starving and bombing them together with their captors? To bring the "low hanging fruit" example, do you think that the three hostages who were waving white flags nearly entirely naked, and who were subsequently murdered by the IDF; do you think that they or their families prefer(preferred) this devastation that lead to their deaths instead of a simple hostage exchange?
What do you think would happen if IDF killed most of Hamas and had their last few forces cornered with no escape, and were getting close to them? Do you think the hostages would not be killed by either their captors or by IDF as collateral damage in such a scenario?
Claims that the systematic destruction of Gaza and genocide(-lite?) serves the goal of bringing back the hostages is such an obvious cover for bloodthirst that it is honestly intellectually-insulting to keep reading it over and over again.
