Huh? What's that got to do with anything? Your argument for the danger was the "access" they'd have to our security procedures. My point is that they already have equivalent access because of all the arab flagged ships that visit our ports regardless of whether this deal happens or not.
If security is so good that we need not worry, then how come even after 911 people have still gotten guns on planes?.
That also has nothing to do with this deal. Explain what it is about the exact tasks that this company will have that make us potentially less secure. Keeping in mind that other arab-owned companies have been operating shipping terminals in the U.S. for years.
The problem is that you don't understand port operations. This isn't letting them in through either the front or back door.
Can you guarantee that the chances of a terrorist supporter or sympathizer working at the ports owned by Dubai is the same as the chance when the British Company owned, honestly?
No. Could be more, could be less. Ownership matters very little, and the type of services this company will be performing are not things that would be of much value to a terrorist.
