Israel has always made some effort to do so; I mean, they could absolutely have killed a few hundred thousand people the last time they fought Hamas, but didn’t. It’s not a political option to do so and the nutballs screaming for Gaza to be wiped out just don’t get it.
Biden (or any President) HAS to say this, even know it’s unnecessary, for the sake of PR. It’s breaking news, but for the consumption of the American electorate. It doesn’t have an effect on what Israel does. I’m sure other allied leaders have said similar things.
Israel has shut off all power and water to Gaza. Is Egypt allowed to send power and water in as per relevant agreements with Israel? Or do they just not care to?
