Actually, they do have to go along with it unless credible evidence is presented to show the company has ties to terrorist organizations. The CONTRACT for port operations came with the company they purchased. You really think we're going to get cooperation from the UAE or any other country if we set a rule saying no "filty arabs" are allowed to have any business dealings with America? Yeah, that's a great way to gain cooperation.
There is evidence out there of this Arab country's ties to terrorist organizations, it's being reported all over the place. And I suspect when all is said and done there's going to be a lot more of it in the coming few weeks.
