I don't want to ignore your post for fear it will lead into an off-topic discussion about the Egyptian military and not the topic at hand even though I can sense you're trying to correlate the two together. And since
@PakSword and the other mods left it, it must be ok with them to at least offer an answer.
Are you aware of the conditions of the peace treaty signed in 1979? Sinai is separated into 3 sectors militarily. Dived the peninsula in 3 sectors starting at the canal zone and the central part and the third at the Israeli border. Starting with the first sector, only a certain amount of defensive weapons are allowed and as sectors get closer to Israel, it becomes nearly only military outpost and a boarder guard patrol. In the treaty, the same applies to Israel's side and all this done for Israel's protection. Ask me if I agree with that and I'll tell you no, of course not, but that's what Sadat, Begin and Carter agreed to in that treaty.
On top of that is the major reason why no mobilization of any of our "fancy" and modern military will be undertaken to the border because it is clearly agreed in the treaty that such an act (for whatever reason, will be considered an ACT OF WAR provocation and the US will respond in kind at its full disposal.) Call it what you like, cowardice, zionist stooges whatever, it doesn't matter to me. The leadership has abided by the treaty and will continue to do it because our intentions (also defined in the treaty) is that Israel NEVER enters the Sinai militarily. It's not for supporting this unfortunate cause as much as it pains me to say that. But there is your answer and I hope it makes sense. No one at this time including the great superpowers like Chine and Russia would want a full military escalation with the US and NATO. Would you?
Egypt has been very aggressive on the diplomatic front with the UN of first getting a cease fire so no more Palestinians are ravagely killed. They've tried 3 times already between Israel and Hamas and are being very aggressive with Israel. Right now, diplomacy is our only choice and we are pushing as hard as possible. You might not like El Sisi and that's fine, but you can't just pack up your forces and threaten war against the US. Please be reasonable. Sorry
