From the White House official web site, which, for some reason, Blogger won't let me link to:
For Immediate ReleaseMay 9, 2007
Office of the Press Secretary
Purpose(1) This directive establishes a comprehensive national policy on the continuity of Federal Government structures and operations and a single National Continuity Coordinator responsible for coordinating the development and implementation of Federal continuity policies. ...in order to ensure a comprehensive and integrated national continuity program that will enhance the credibility of our national security posture and enable a more rapid and effective response to and recovery from a national emergency.
(b) "Catastrophic Emergency" means any incident, regardless of location, that results in extraordinary levels of mass casualties, damage, or disruption severely affecting the U.S. population, infrastructure, environment, economy, or government functions...
Think: Earthquake, hurricane, attack, or ANYTHING that Bush deems might "disrupt" the U.S. population, environment, etc. Hmmmm. Wonder which one he'd choose? After all, he is the Decider.
(e) "Enduring Constitutional Government," or "ECG," means a cooperative effort among the executive, legislative, and judicial branches of the Federal Government, coordinated by the President ...
Okay. Check that out carefully. Bush calls all the shots. The president, and only the president, "coordinates" everything. Yes, everything. He didn't call himself the Commander Guy for nothing.
(6)...In order to advise and assist the President in that function, the Assistant to the President for Homeland Security and Counterterrorism (APHS/CT) is hereby designated as the National Continuity Coordinator.
The APHS/CT at the moment is Ms. Frances Fragos Townsend. She'd be his Number Dos in the event of a "disruption". Bush and Townsend would be quite a team.
According to Wikipedia, during an appearance on the May 8, 2007 edition of CNN's "Situation Room", she acted as an apologist for the Bush Administration. However, I'm pretty sure neither one of them would apologize to us for anything they would undertake in the event of what King George would calculate, er, rule...um...regard as "a catastrophe".
