People may criticize America World Police, and the American military spending and posturing, but this is a perfect opportunity to put it to good use. If Biden et al in Washington actually cared: financial and military aid to Isreal is frozen; they obviously don’t need it. Deploy a Marine Expeditionary Unit stocked with aid into the Mediterranean (maybe supplement with a Navy hospital ship, perhaps a carrier strike group in “support.” Speak softly and carry a big stick).
Declare that Marines will be providing aid to Gaza via amphibious landing and helicopter. Make it clear they’re sent in peace but should one Israeli bullet even graze a Marine or their equipment, the US will not have to kill 30,000 civilians to get to those responsible.
I’d bet a dollar Netanyahu (or any other world leader) would start behaving more prudently. And it would cost nothing: MEUs will be sailing regardless, Israeli aid will be transferred to Gaza aid, funds already earmarked will simply be redirected.
I don’t think he literally wants to, otherwise he could do it himself, but he’s certainly not doing much to prevent it
