Why Egypt will never open their border to Gaza

We know that Israel wants to ethnically cleans Gaza. They are openly calling for that (and worse). Their plan is to push them all into the northern Sinai (I guess the irony of pushing a slateless people to wander for years in the Sinai desert as been lost on the government of Israel).

Probably less than one in a thousand Americans are even aware that there is an ISIS affiliate in Egypt.
Even fewer know any of the details behind this insurgency because outside of one incident, the American news media has ignored it. Which is why it is interesting.
During my time on this Earth I've learned that the things the news media ignores are the most significant.
