It might have made Egypt more willing to open its border with Gaza, but could it really absorb 1-2 million refugees, as Jordan once did?
At some point the Egypt-Israel relationship could deteriorate and Israel could expand in that direction again.
Overall expansionist/conquest urges are back in with Russia, US under Trump and Israel. We will probably see China also get into the act.
I agree that Israel harbors Zionist destructive ambitions, but it doesn't really extend beyond "Greater Israel" which is the extent of Israel in Biblical times under King David and King Solomon. That does not extend in Egypt's direction, but it does include Lebanon, Syria and Jordan, so it's no coincidence that Israel has pushed in those directions (southern Lebanon, Golan Heights, and the West Bank).
Talking about Israel, the 150th country in the world in size, in the same breath as China, Russia and the US - five of the largest countries in the world, is very weird.
It doesn’t matter what size Israel is. It has a super equipped army unlike any other country in the region and its population is growing while many countries around it are failed/fragile states (eg syria and Lebanon and sort of Egypt.). And if Jordan is forced to take a few million Palestinians from the West Bank it could become a failed/fragile state too.
