As a follow-up to the previous entry.

A Miami company has sued to block the outsourcing of port operations. The do not want to become an "involuntary partner" with Dubai's government.

...

The Miami subsidiary, Continental Stevedoring & Terminals Inc., said the sale to Dubai was prohibited under its partnership agreement with the British firm and "may endanger the national security of the United States." It asked a judge to block the takeover and said it does not believe the company, Florida or the U.S. government can ensure Dubai Ports World's compliance with American security rules.

I am not sure the U.S. Government can ensure any sort of compliance (U.S. or foreign) with American security rules. Refusing to proceed with this sale might be a good start.
