How many superpowers does government need when combating natural disaster?

The hurricane Sandy. My sister from NJ is saying how bad it is there. But she has been in KY. Power out a week later. I know it is a horrible disaster, but why blame government? Are they not lucky the nuclear plants withstood the storm? After Katrina, people could not enter the city for 3 to 6 weeks. Tornados with entire towns wiped out. Joplin, MO. Cant be fixed in a week.
How can we blame government for natural disaster? I think the relief has been good and quick, for the amount of lives the storm has affected.
