I want to commend to your attention The Tragedy of the American Military by James Fallows. This is a fairly lengthy magazine essay, which I won't attempt to summarize except to say that the spine of the argument is the disconnect between the U.S. military and the general public; and the diverse failures and waste this engenders. I'll give you an excerpt so you get the flavor. Do read.
Ours is the best-equipped fighting force in history, and it is incomparably the most expensive. By all measures, today’s professionalized military is also better trained, motivated, and disciplined than during the draft-army years. No decent person who is exposed to today’s troops can be anything but respectful of them and grateful for what they do.
Yet repeatedly this force has been defeated by less modern, worse-equipped, barely funded foes. Or it has won skirmishes and battles only to lose or get bogged down in a larger war. Although no one can agree on an exact figure, our dozen years of war in Iraq, Afghanistan, and neighboring countries have cost at least $1.5 trillion; Linda J. Bilmes, of the Harvard Kennedy School, recently estimated that the total cost could be three to four times that much. Recall that while Congress was considering whether to authorize the Iraq War, the head of the White House economic council, Lawrence B. Lindsey, was forced to resign for telling The Wall Street Journal that the all-in costs might be as high as $100 billion to $200 billion, or less than the U.S. has spent on Iraq and Afghanistan in many individual years.
Yet from a strategic perspective, to say nothing of the human cost, most of these dollars might as well have been burned. “At this point, it is incontrovertibly evident that the U.S. military failed to achieve any of its strategic goals in Iraq,” a former military intelligence officer named Jim Gourley wrote recently for Thomas E. Ricks’s blog, Best Defense. “Evaluated according to the goals set forth by our military leadership, the war ended in utter defeat for our forces.” In 13 years of continuous combat under the Authorization for the Use of Military Force, the longest stretch of warfare in American history, U.S. forces have achieved one clear strategic success: the raid that killed Osama bin Laden. Their many other tactical victories, from overthrowing Saddam Hussein to allying with Sunni tribal leaders to mounting a “surge” in Iraq, demonstrated great bravery and skill. But they brought no lasting stability to, nor advance of U.S. interests in, that part of the world. When ISIS troops overran much of Iraq last year, the forces that laid down their weapons and fled before them were members of the same Iraqi national army that U.S. advisers had so expensively yet ineffectively trained for more than five years.
