Your logic has too many holes. If the Nazis had managed somehow during WW2 to purchase sensitive installations in the US we should still have let the deal go through to avoid risks that future potential companies might not "pony up"? It's Bush after all who calls himself a wartime president and claims to be fighting the very same elements that could easily infiltrate these ports and do us harm.

Please show me where we declared war on the United Arab Emirates--I must have missed the announcement.
