The government of this nation will do its part, as well. Our cities must have clear and up-to-date plans for responding to natural disasters, and disease outbreaks, or a terrorist attack, for evacuating large numbers of people in an emergency, and for providing the food and water and security they would need. In a time of terror threats and weapons of mass destruction, the danger to our citizens reaches much wider than a fault line or a flood plain. I consider detailed emergency planning to be a national security priority, and therefore, I've ordered the Department of Homeland Security to undertake an immediate review, in cooperation with local counterparts, of emergency plans in every major city in America.
