two, if the question is asked ‘what does Israel do - and therefore Jews do - to protect itself and themselves against people sworn to kill their state and all of them, in the face of recent murder, rape, desecration and kidnapping by Hamas?’, the answer is always (some variation of) the chant “but it’s disproportionate!”. That’s despite every effort that Israel takes to warn of action; despite Hamas shielding itself behind civilians; despite Hamas’s tactics of hiding in and beneath hospitals and other facilities; despite Hamas placing rocket sites by desalination plants; despite Hamas blocking evacuation and forcing civilians back to areas warned about; despite any recognition that Hamas is a cipher for Iran’s genocidal ambitions. And on and on.
I think, @WhileMyDishwasherGentlyWeeps that there are some legitimate concerns that have become more apparent as this operation in Gaza has gone on. The civilian death toll is extraordinarily high, for various reasons including Hamas using human shields, the population density and the inability to evacuate to neighbouring countries. The threat of Hamas to Israel is of course severe, but that cannot mean a blank cheque in terms of actions taken to eliminate it. I think it is hard to be convinced that Israel is doing everything it can to limit losses when the rhetoric of the Israeli government suggests otherwise, along with their actions in the West Bank.
However, it is correct to say that there are people who were criticising Israel's response before they even took any retaliatory action, and some who were, despicably, celebrating Hamas. There's also been a shocking lack of interest in bringing Hamas to justice for its terror attack and for the ongoing hostage situation, and as time has gone on, a creeping minimisation of the actions of Hamas from some has turned into something like a sneaking regard. There is, undoubtedly, an antisemitic undertone (or even overtone) to a lot of this.
The whole situation is awful, heartbreaking, there are terrible faults on both sides, and while it is undeniably true that Hamas need to be dealt with, it's unclear if Israel's current course can continue to be tolerated. The US are already signalling a change of tactics is needed.
