Actually, the deal IS extraordinary in the sense that the U.S. has never engaged a state-operated/owned business in this degree of effort before. In that regard, we are selling to the UAE by selling to their state-owned/controlled business.
And, the deal IS extraordinary in the sense that this foreign state, known to associate in some fashion with terrorists (they recognize the Taliban, they do not recognize Israel, they have laundered and probably still are money for terrorist groups, they are known to traffic in weapons, and more) will be keeping all records in the UAE, not within the U.S. as to their operations here, and that they will have access to U.S. national security information that is privileged and classified and otherwise possible to be compromised by...terrorists.
These are not hysterical questions but realistic and very important ones to ask. The "physical operations" involve highly specific port, shipping and security information, along with access to the interior of the U.S. via shipping by service and goods.
The US isn't selling anything here. The selling and the buying is between two foreign companies, P&O and DPW. Since the deal involves the logistics movement of goods though US ports-of-entry, it was vetted and approved by many US government agencies headed by the Commerce department. The only thing extraordinary here is what's being drummed up by the press.
