More important, protecting New Orleans is the classic example of something we can't afford not to do. Those who believe New Orleans can survive as a smaller city and still serve the rest of the country as a port are mistaken. Louisiana continues to erode: the equivalent of roughly a football field melts into the sea every hour.
If nothing is done, the city will become a fragile walled island under constant assault. Nor can the port move to Baton Rouge. The port runs along almost 70 miles of river, much of which will be threatened.
Every time I have doubts, I stumble on to something like that, and then I feel confident again that we really are a World Class city--or at least we must be, if America is to remain a World Class nation.
