Either kill the deal or else make it a condition of the deal that if it ever happens that a terrorist attack in the U.S. succeeds because of failures of port security at ports overseen by Dubai Ports World, the U.S. will immediately seize all U.S. assets of Dubai Ports World and also invade the United Arab Emirates and turn it into a Disney attraction for gawking infidel tourists.
No conditions. This deal is bad for the USA.
Sounds like a plan to me.
