A short-term PR hit trying to force the UN to leave may or may not be worse for PR than the reports of actions in the field over the following months. One is very short-term and the other is very much not.
But really I guess that’s where we just agree to disagree on priors. Sadly, given the evidence of the last six months, I’m not very confident that the IDF is as conservative on decisions of proportionality or care as they were a decade (or two) ago. All evidence points to even close allies having very serious (non-public) questions on proportionality on a regular basis, and given the civilian leadership (who decide military leadership) for the last decade(ish) I don’t find that particularly surprising :(.
