Looming Crisis at the Pentagon

That's the title of an essay by Chalmers Johnson that you have to read. Here's part of the introduction.

Given our economic crisis, the estimated trillion dollars we spend each year on the military and its weaponry is simply unsustainable. Even if present fiscal constraints no longer existed, we would still have misspent too much of our tax revenues on too few, overly expensive, overly complex weapons systems that leave us ill-prepared to defend the country in a real military emergency. We face a double crisis at the Pentagon: we can no longer afford the pretense of being the Earth's sole superpower, and we cannot afford to perpetuate a system in which the military-industrial complex makes its fortune off inferior, poorly designed weapons.
