Seems the emerging U.S. position is that Israel's right to defend itself has limits. Airstrikes against civilian centers can be shrugged aside, but undeniable human rights abuses like removing safe access to water are unacceptable.
Regardless of your position, Israel
does have a right to defend itself against terrorist activities, which is made difficult because of how Hamas operates. It does not, however, have carte blanche to ruin what's left of Gaza, and I'd argue that as the superior economic/militaristic/political force between the two states, Israel has a duty to build up Palestine as a partner if Israel has any long-term interest in regional peace and justice. What we're being shown now is that Israel does not have that interest, and is instead sprinting towards eliminating Palestine for good. So deeply devastating for people on both ends, while the ultimate victim still remains Palestine.
