You got this port deal correct. Let me describe the deal by using the airline industry. For example, British Airlines flys into Bush Intercontinental Airport in Houston, Texas and docks at their terminal. The airport owns the terminal and British Airlines is leasing the terminal. Bye the way, all security is performed by Americans. Along comes UAE and buys out British Airlines. Nothing changes because British Airlines stills flys into Bush Airport except the ownership of British Airlines is now UAE. This is the same for the port deal.
Thanks for that post. It will help to clear this up. Unfortunately, the facts get in the way of some people.
