If Al Qaeda uses long-range ground to ground missiles captured from Assad inside Syria to blow up Egypt’s Aswan Dam, the resulting chaos and destruction would give the Muslim Brotherhood and Hamas a chance to take on the Egyptian Army.
Such a war would need a large PR news media campaign for them.
That would be a significant attack.
Well... I respect your opinions a lot, but, how big are those warheads? It normally takes specially designed, large bombs, to breach a substantial dam, and the Aswan is a VERY substantial dam.* I’d say there was no chance of success, unless maybe the water level behind the dam was critically high, and you hit the thing just right with something like a 10x the size “Upkeep” bomb, or a modified latest generation (and big) bunker buster — maybe a series of them, all in the same exact spot, maybe at the spillway. Taking a chunk out of the main dam in a significant way probably requires a small nuke.
