Planes from Muslim countries land in the U.S. every day. Personally I find that more worrisome than an ally's state-owned company managing the berthing of ships. Cargo and passengers will still be subject to U.S. security. Do I prefer each country managing its own ports? Yes, but for some reason, U.S. companies run other countries' ports and non-U.S. companies run some of ours.
Uh.. no we don't... in fact I don't think the US even has a port management company at all.
