Yes. With the acquision of P&O Ports, Dubai Ports World (a single, state owned entity) will be the third largest port operator in the world.
Maybe someone can educate me about how Dubai is organized as a "country" in that I had the belief that there was control by a royal family of some kind or other and that the "nation-state" concept is because it is a "kingdom." That being said, the nation is in fact a group of controlling individuals. If I am wrong, I will admit it, but I think that the use of the concept of a country buying this port seems hollow and not quite accurate.
The answer to this question becaomes very important because of this issue.
For exasmple, who decides for Dubai whether we are allowed to stay there with the military?
