We have foreign registered ships coming into the US every day and no one has voiced concerns. Foreign nationals routinely work on US installations overseas. Before I stick my neck out on this, I would want to know what port facilities are affected, the size of the facilities, where they are located and the arrangements for monitoring and inspection.
From the 2/12 AP report:
The Bush administration considers the UAE an important ally in the fight against terrorism since the suicide hijackings and is not objecting to Dubai Ports World's purchase of London-based Peninsular and Oriental Steam Navigation Co.
The $6.8 billion sale is expected to be approved Monday. The British company (London-based Peninsular and Oriental Steam Navigation Co.) is the fourth largest ports company in the world and its sale (to Dubai Ports World) would affect commercial U.S. port operations in New York, New Jersey, Baltimore, New Orleans, Miami and Philadelphia.
Just a few major ports involved, but what the heck, business is business, right? -- and we know that Muslim nations never attempt to use their unearned oil booty to spread Islam here -- just look at Saudi Arabia.
In other news, "Qatar-based Al-Jazeera Television has announced a deal with the Dubai-based ARY Digital Network to launch an Urdu-language satellite TV channel targeting over 110 million Urdu speakers globally, the Qatari newspaper Gulf Times reported on 26 January." Ho-hum, not a problem; Dubai is an ally, and Al Jazeera is simply an objective, unbiased broadcasting company.
I can't help you with the details of "arrangements for monitoring and inspection," but I would suspect the security is about as effective as it is on our southern border. Just a hunch.
