Despite the best efforts of a former DHS inspector general ("While the United Arab Emirates is deemed by the Bush administration to be an ally in the war on terrorism, we should all have deep concerns about its links to terrorists."), I remain unconvinced. To quote David Sanger:

But the security of the ports is still the responsibility of Coast Guard and Customs officials. Foreign management of American ports is nothing new, as the role already played by companies from China, Singapore, Japan, Taiwan and trading partners in Europe attests.

While critics of the deal have raised the specter that it might open the way to the "infiltration" of American ports by terrorists from the Middle East, the Dubai company would in most cases inherit a work force that is mainly American, with hiring subject to the same regulations as under the current British management.

Among the many problems at American ports, said Stephen E. Flynn, a retired Coast Guard commander who is an expert on port security at the Council on Foreign Relations, "who owns the management contract ranks near the very bottom."
