The American Conservative is a mixed bag, to put it mildly, but this piece by Andrew Bacevich is well worth reading. Bacevich points out how rarely the faith of the American policy elite in military force has actually been rewarded with success. The key quote:
An alternative reading of our recent military past might suggest the following: first, that the political utility of force—the range of political problems where force possesses real relevance—is actually quite narrow; second, that definitive victory of the sort that yields a formal surrender ceremony at Appomattox or on the deck of an American warship tends to be a rarity; third, that ambiguous outcomes are much more probable, with those achieved at a cost far greater than even the most conscientious war planner is likely to anticipate; and fourth, that the prudent statesman therefore turns to force only as a last resort and only when the most vital national interests are at stake. Contra Kristol, force is an “instrument” in the same sense that a slot machine or a roulette wheel qualifies as an instrument.
To consider the long bloody chronicle of modern history, big wars and small ones alike, is to affirm the validity of these conclusions.
