The Pentagon, and the DOD leadership and management as a whole, is completely and utterly broken. Not only are they a bunch of weasels, they are, for the most part, sniveling, incompetent, cowardly weasels.
As example #1, the Air Farce is still slow-rolling the light attack aircraft program into oblivion. We've only known we needed these ground support planes for 17 years now. That's 4 world wars, if you're counting. Read Commander Salamander's thoughts on the subject.
This leads me to something I've been contemplating for quite some time now. The Pentagon concentrates all its attention, money, and cronyism on preparing (badly) for "the big one." This degrades the existing forces, in addition to using sledgehammers to kill mosquitoes.
