All of those canals were basically the same canal that was an attempt to link the Red Sea to the Nile River, which looking back was a pretty risky thing to do as the Red Sea is at a higher elevation than the Nile. I'm talking about a canal that cuts straight through the Sinai from the Mediterranean to the Red Sea just like in our OTL. When is such a thing possible, and what's likely to be the effects?
I think Egypt is probably going to have a much easier time trading with Rome, Nubia, Axum, and India and control over the peninsula will be more important than in OTL due to the lucrative trade. Transport around Egypt may get easier, especially if they complete and maintain the Canal of the Pharaohs. Will Egypt become more maritime focused?
