I would have to ask the question, what is wrong with United Arab Emirates running the 6 US major ports. What difference would it be than allowing the current London-based company? Both are friends of the United States and if economically it is a better deal for the United States, why not? That being said, this decision should be educated and not political and the cynical side of me always thinks decisions such as these are political. There must be a strong back up system in place to ensure supply chains will not shut down due to terrorism. If these ports are shut down due to terrorist activity the effect could be detrimental on all of the goods shipped into and out of United States ports. However, regardless of who manages the ports, terrorism could happen since no city, state or nation is fully immune to terrorism and a solid disaster plan must be in place.
