I don't understand his angle here. He clearly has some sort of agenda, but I haven't figured it out. Maybe he's betting that this will turn some Democrats and moderates against Biden? But that requires believing that Netanyahu is telling the truth, which I don't think a lot of Israel supporters necessarily do.
Either way, this is weird. Maybe he's talking about the bombs that weren't sent for Rafah? But getting pissed about one halted shipment out of everything they've been given is just fucking hilarious.
My guess -- he's aware his support is dwindling, and he's trying to salvage it by blaming everyone else. Or, he's daring the US to stop all shipments, but that would probably destroy his remaining support too.
