we’re going to attack those investigating war crimes

Do they think this is a winning strategy while also admitting Israel is causing a famine?

Israel is a state actor that has not signed on to the ICC, just like the US. Hamas is a non-state actor over which the ICC claims jurisdiction, just like the Taliban and any number of other terrorist groups. The US is really afraid of setting a precedent here that might impact it in the future.

Long way of saying it is supporting and aiding genocide that it desperately wants the world to go back to ignoring like the last seven decades.

How specifically are US interests served by a genocide of Palestinians? They aren’t. The US doesn’t care about Palestine at all, but it would be better off if Israel weren’t doing the indefensible. The US just wants Israel as an ally to assist in projecting power in the Middle East.

I sympathize with the desire to end what Israel is doing, but the first step is understanding the national interests at play. It’s not an excuse for anything, but it’s necessary to understand the dynamics at play in order to try and change those dynamics.
