As for the corporations so eagerly lapping up the contracting dollars, there's no conspiracy -- it's just the good old profit motive. If the White House wants to sell off U.S. foreign policy, someone's going to buy it. Prince, the former Navy SEAL who founded Blackwater, is straightforward about his company's goal: "We're trying to do for the national security apparatus what FedEx did for the Postal Service."

Since FedEx rendered the post office irrelevant for all but the most trivial forms of mail, this means you can kiss our national security apparatus goodbye.
