The Suez is at basically the one point it makes sense to build it. The next closest is off the Gulf of Aqaba and that's right on the border of Egypt and Israel.

The Suez is at basically the one point it makes sense to build it. The next closest is off the Gulf of Aqaba and that's right on the border of Egypt and Israel. It really doesn't make sense for Egypt to go through the trouble of cutting a second one on the one in a million shot a ship gets stuck like this. The usual answer is just make sure they don't get stuck rather than spend the billions of dollars cutting a second canal would cost. Even if Egypt was somehow charged the losses for this screw up that probably wouldn't be enough to make it worth cutting a second backup canal.
