Individual self-defense is legally restricted in your (and my) country because you can rely on the state to take up the fight once the immediate threat has passed. If someone tells you that they're going to come and shoot you at some point in the future, you call the police, and the police will pre-emptively use force against them by putting them in jail. At least that's the theory. I agree that Israel are probably being recklessly indifferent to civilian lives and likely committing war crimes, but Hamas explicitly has the genocide of the Jews as their founding principle. For Israel to be safe, Hamas has to go. I can't see any other way this ends, and with the way Hamas embeds themselves within the civilian population, collateral damage is inevitable. Although, to repeat, I do think Israel need to do more to minimise it.
