Hurricane Katrina made landfall on the Gulf Coast Aug. 29, 2005,
devastating New Orleans and, as the levees failed and the darkened city
flooded, plunging the city into a period of civil disorder that shocked
America. Unable to provide effective help and accused of bungling relief
operations, the Bush administration suffered lasting political damage.
Perhaps more profoundly, America discovered the limitations of its ability
to protect against natural disasters.
