No. Next question?
Facts are your friend, find some.
The ports are owned by ports authorities, which are public entities set up to own the public assets like ports. The ports have terminals, many many terminals. Some terminals are set up by private companies to handle their own shipments, some by shipping companies, and some by management companies.
The ports authority wants to have terminals at the ports, so they can make money on taxes on shipments, and have employment. So they lease space at the ports to companies that will put terminals in and operate them. This makes the government money in the lease, and money from operations.
So no, there is no chance of anybody claiming "national sovereignty".
BTW, many many buildings and property in this country are owned by foreign governments, and they can't claim "national sovereignty" over those either, even though they own them. Any more than you can because you own your house.
The only place a government claims national sovereignty in a foreign country are the official consulate buildings and property.
I see nobody "leaving out" the ownership of DPW. Every company has owners. P&O was owned by a large number of stockholders, some of who were undoubtably leaders of muslim countries. Maher Terminals is owned by the Maher family. DP World is owned by a holding company controlled by some shieks who are also the rulers of some of the emerites in the UAE.
I don't support governments owning private business, but it is an unfortunate fact of life that throughout the world governments have taken over companies. Many countries have public control over oil companies. Most airlines are national airlines. We have the U.S. Postal Service, among other things like Amtrak. We do try to make a fiction that we don't directly own companies.
I listened to Limbaugh for the whole first hour and he never once mentioned it. He kept saying "a foreign company". Never a "foreign company partly owned by the govt. of Dubai".
