If any overarching conclusion emerges from the Afghan and Iraq Wars (and from their Israeli equivalents), it's this: victory is a chimera.

In present-day America, expressing reverence for those who serve in uniform is something akin to a religious obligation. Everyone professes to cherish America's "warriors." Yet such bountiful, if superficial, expressions of regard camouflage a growing gap between those who serve and those who applaud from the sidelines. Our present-day military system, based on the misnamed All-Volunteer Force, is neither democratic nor effective. Why has discussion and debate about its deficiencies not found a place among the nation's political priorities?

For the majority of contemporary Americans, the essence of life, liberty, and the pursuit of happiness centers on a relentless personal quest to acquire, to consume, to indulge, and to shed whatever constraints might interfere with those endeavors.

To divine the course of world events, you'd do as well to probe the entrails of dead animals. Better still, ask your hairstylist. She will be at least as insightful and probably more entertaining a prophet than anyone you can read in Foreign Affairs or the op-ed page of the Washington Post.

The U.S. military today garrisons the planet in a fashion without historical precedent. Successive administrations, regardless of party, justify and perpetuate this policy by insisting that positioning U.S. forces in distant lands fosters peace, stability, and security. In the present century, however, perpetuating this practice has visibly had the opposite effect. In the eyes of many of those called upon to "host" American bases, the permanent presence of such forces smacks of occupation. They resist. Why should U.S. policymakers expect otherwise?

The United States military is undoubtedly the world's finest. It's also far and away the most generously funded, with policymakers offering U.S. troops no shortage of opportunities to practice their craft. So why doesn't this great military ever win anything? Or put another way, why in recent decades have those forces been unable to accomplish Washington's stated wartime objectives? Why has the now 15-year-old war on terror failed to result in even a single real success anywhere in the Greater Middle East?

Ideology makes people stupid.
