The brutality of the Hamas attack on Israel persuaded Biden to tolerate a large number of Palestinian civilian casualties in Gaza City so long as the Israelis made reasonable efforts to segregate civilians from militants and provide them with humanitarian aid. The initial phase of the war is reaching its conclusion, however, and the agreement between America and Israel is probably going to end, based on the signals coming out of the Israeli government.
In light of world opinion and simple human decency, Biden needs to make it clear that America will provide neither material aid nor diplomatic cover for either an Israeli occupation of indefinite duration or a large-scale assault on the supposedly safe areas in the southern part of Gaza. As far as we’re concerned, the point of the invasion was not to annihilate the population nor to oppress it in perpetuity; it was to replace a group of terrorists with a regime that could co-exist with Israel and make Gaza flourish.
