It really doesn't matter who runs the American side of the port. Once a nuclear bomb is loaded into a shipping container at the far side and it sails into a US port, it can be detonated on the ship with the desired effect. We need to screen cargo containers when they are loaded at the foreign ports. Those ports represent the real vulnerability.
DHS scans (some) shipments in UAE *now* for that reason. Will we keep that ability if this deal goes south?
