Ordinary indecision is unlikely to keep Suez from being built. Its route offers such obvious value to Egypt and international commerce that investors and states have powerful reasons to complete it. An impassable mountain range or exceptionally obstructive political control are offered as changes large enough to stop construction. Either cause would create additional historical consequences of its own, making confident downstream predictions difficult.
