re: #91 Dark_Falcon

True, it is a rare, rare event.

Katrina was such a grave situation that NATO said this:

NATO was prepared to send troops, but the U.S. government has not issued a request for personnel.

Essentially, NATO said that the US could have declared an Article 5, and NATO would have intervened militarily.

It would have been classified as an attack on the United States. It likely would become a resurrection of the Military Districts from 128-140 years earlier.
