reports are sent instantly to a computer at city hall, where the database is linked to aerial images of every address, both before and after.

When the reports are in, they will know how many billions it will take to rebuild, but not where that money is coming from.

Mike Centineo showed us, at his house, that you can't appreciate the loss until you walk through the door. He lost pretty much everything in his home. "We've lost a lot. What hurts is family photos. They went under water and I pulled them out to try to salvage what I could," Centineo says.

Centineo says he understands, probably better than any building official ever has, what the victims of Katrina are going through. "I'm one of them, that's true, I'm one of them."

He is one of about 400,000 people still unable to come home. That's the worst part now, the deflation of the Big Easy.

There are too few people to pay taxes or keep businesses going. The world's largest domed stadium doesn't have a football team; In New Orleans, these days, not even the Saints go marching in.

Meffert has some clear feelings on whether the nation should commit billions of dollars and several years to protect the city.

"Is it commit or invest? I mean this is the thing that that people miss. The country has to decide whether it really is what we tell the world what we are. Or are we just saying that? Because if we are that powerful, if we are that focused, if we are that committed to all of our citizens, then there is no decision to make. Of course you rebuild it," says Meffert.

For much of 2005, the news out of Iraq has overshadowed what has been going on in Afghanistan, where 18,000 U.S. troops are still fighting and dying along the Pakistan border in battles with the Taliban, al Qaeda and other Muslim extremist groups.

The rest of Afghanistan, at least compared to Iraq, appears relatively peaceful. But the country is facing another threat to its stability — its growing addiction the production and trafficking of heroin, which is controlled by some of the most powerful people in the country.
