They’re literally doing final solution shit in front of our eyes.
If they intended to maximize civilian deaths they aren't going about it very well, they are still calling people before strikes and doing "door-knocker" strikes in rooftops before the real ones. This is war, where many civilians die, not systemic eradication, where every civilian dies.
It's also worth noting that 20% if Israeli citizens with full rights are Palestinian/Arab and live mostly peacefully. Gaza is being attacked because they are a belligerent in a war, not because of eugenics or a Nazi-style "final solution."
