Middle Eastern Country to run U.S. Ports

Ok, it's a UAE owned business. I was pretty sure it was, but I didn't want to say it because I didn't know for sure.

Do we have a governmental policy that restricts business deals with Middle Eastern companies if they are owned by a Middle Eastern government? People are so up in arms about Arabs managing our ports, but what would change? All kinds of things are already illegally smuggled into the states - things like drugs. If we knew all the gaping holes in security I don't think any of us would feel safe.
