OK? The US aid arrangement is also part of the whole thing, though.

[EDIT] Oh damn, when did Jordan rocket up the list of US aid recipients? I gotta start keeping up with geopolitical shenanigans again, I'm clearly behind the times. But yes, the Egypt thing was, if not publicly the case, one of those open-secret things that're taken for granted in poli-sci and policy circles, like "Israel has nukes", or "the US removing MRBMs from Turkey was part of the deal for keeping Soviet nukes out of Cuba". The US pays Egypt not to mess with Israel.

It’s as useful as the money they used in Afghanistan. This isn’t the 70s anymore. Egypt isn’t incentivized to battle Israel, and Israel isn’t incapable of defending itself.

It wasn't incapable then, either. Clearly. But this takes some of the heat off them, and discourages Egypt from permitting—or encouraging—non-conventional anti-israel forces within its borders, or abroad, even as its domestic politics shift (no-one wants to shut off the money hose).
