The DP WOrld company already works directly with our government on security -- they inspect the containers in foreign ports before they come here.
The management of the ports will still be done by the same US subsidiaries that do so now, with the same people in charge, so the contacts they have with the Coast Guard will not change.
The same contacts already exist with MANY foreign companies, some owned by foreign governments, that operate various terminals at ports throughout the country.
We can't have a rational discussion until everybody has the actual facts.
Your post is #608; they've had the facts for 600 posts; can't you see the difference? :-)
