I’m not saying anything out of Benjamin Netanyahu’s mouth can be trusted at all, but him whinging about the Biden Administration withholding weapons shipments certainly does make an argument against your claims.
The US is dumping nearly it’s entire weapon production, which isn’t as much as you might think, into Ukraine and Israel. Israel in particular is excessively spending ordinance faster than it can be produced to murder civilians and pound Gaza into dust, which keeps leaving them waiting impatiently on new shipments.
Now that Israel is shifting focus on bombing and invading Lebanon, they anticipate needing even more weapons because Lebanon is bigger and Hezbollah has actual defenses, hence even more zionist whinging.
He’s not withholding shit, he’s just not delivering fast enough to the rabid Zionist’s taste despite his best (more like worst) effort.
