If you have a major disaster involving hundreds of thousands, or in this case millions of people, whether it be a natural disaster or an act of terrorism, the first 72 hours are going to be totally chaotic no matter what you plan to do.

This may sound trite, but bad things happen to good people, and when you're facing terrorism, natural disaster, you can have every wonderful plan in place, but I am a realist.

Sometimes it takes a natural disaster to reveal a social disaster.

Climate is always evolving, and natural disaster have always existed.

The president's very right about one thing: When you have a disaster of that scale, whether it be natural or a terrorist attack, there's only one part of our entire government, state or local, that is equipped to handle it, and that's the U.S. military.

If there were a major earthquake in Los Angeles, with bridges and highways and railroads and airports all shut down and huge buildings collapsing, I don't care how much planning you do, the first 72 hours is going to be chaotic.
