That's quite profound, my friend. I honestly don't think the zionist are in any way, shape or form interested in dragging Egypt into a war with them, regardless of their super duper alliance with the United States and the empowerment that alliance gives them. There is still a peace agreement that they must abide by. And while they've pushed the limits of that agreement with their recent incursion of the Philedelphi Corridor, it's still not at the level of an act of war, not even close TBPH.
And to be even more honest with you, it would be really difficult for any Egyptian leader (especially Sisi as you quite well know) to base any developmental aspirations on the occupation of Palestine. As harsh and as insensitive as that sounds, it's the reality and something any good leader would most certainly struggle with.
But I like how you brought it to the table. Certainly something to think about for sure.
