Josh makes the point that Gdub is not responding to a natural disaster, but rather a political disaster for him.
Maybe you want to spend $200 billion on rebuilding the Delta region too. Fine. Something like that will probably be necessary. But don't fool yourself into thinking that what's coming is just a matter of a different chef making the same meal. This will be Iraq all over again, with the same fetid mix of graft, zeal and hubris. Cronyism like you wouldn't believe. Money blown on ideological fantasies and half-baked test-cases.
You could come up with a hundred reasons why that's true. But at root intentions drive all. You'll never separate this operation or its results from the fact that the people in charge see it as a political operation. The use of this money for political purposes, for what amounts to a political campaign, tells you everything you need to know about what's coming.
