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.

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.

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?

Memorial Day orators will say that a G.I.'s life is priceless. Don't believe it. I know what value the U.S. government assigns to a soldier's life: I've been handed the check. It's roughly what the Yankees will pay Roger Clemens per inning once he starts pitching next month.

Are there any military actions that the president of the United States may not order on his own authority? If so, what are they? Bit by bit, decade by decade, Congress has abdicated its assigned role in authorizing war. Today, it merely rubberstamps what presidents decide to do (or simply stays mum). Who does this deference to an imperial presidency benefit? Have U.S. policies thereby become more prudent, enlightened, and successful?
