It may seem a wonky piece of trivia that a man named Michael Brown withdrew his nomination last week to be the Pentagon’s acquisitions chief. But in fact, it’s a national security disaster, a retreat from a promise of major reform in the way the U.S. military buys weapons, a process currently controlled by one of Washington’s most sclerotic bureaucracies. It is also worth noting that Brown’s withdrawal was forced by an enabler of that bureaucracy.
