I gather there is some concern in America about an “Arab” company taking control of their ports. I don’t see what the fuss is: what difference does the nationality of the shareholders make? The Polish government is also worried about foreign ownership, of banks, in particular. Apologies for the why-oh-why’s but why can’t capitalists accept the consequences of private ownership and the free flow of capital? If you allow private ownership of banks, ports, military research companies, governments etc� then you have to accept that the owners may have their own plans.

See Dennis the Peasant for some research on the topic.
