From MSNBC and Newsweek, for the price of one month in Iraq we could restore the gulf coast:

Most people in the Netherlands live below sea level, and the country’s major cities are in continual danger of being washed away. Or they would be, if Dutch engineers weren’t so good at designing levees and floodgates to keep storms at bay.
. . .
The Dutch are, no argument, the world’s experts. Which raises a question as U.S. politicians and bureaucrats dicker over whether and how to fortify New Orleans against future storms: why not hire the Dutch?
. . .
Hans Vrijling, a renowned authority on flood control who designed part of the Dutch system, says it should be possible to protect New Orleans—even low-lying sections—from storm surges more than 10 times Katrina’s. The price tag: less than $10 billion.
. . .
Vrijling, for one, can’t understand what the Corps is going to study for so long. The technology already exists and has been tested over decades in the Netherlands. He says Dutch and American engineers, working together, would need only “a couple of months” to draw up a detailed plan. “If we had the will and one month’s money from Iraq, we could do all the levees and restore the coast,” says Ivor Van Heerden, a Louisiana State University hurricane scientist who warned for years about a Katrina-like disaster. “We can save Louisiana. It is very doable.”
