Why do terrorist attacks that kill a handful of Europeans command infinitely more American attention than do terrorist attacks that kill far larger numbers of Arabs? A terrorist attack that kills citizens of France or Belgium elicits from the United States heartfelt expressions of sympathy and solidarity. A terrorist attack that kills Egyptians or Iraqis elicits shrugs. Why the difference? To what extent does race provide the answer to that question?

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?

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?

Time and again-from the collapse of the Soviet Union to the events of 9/11 to the onset of the Arab Spring-events have caught the experts, whether in government or on the outside, completely by surprise. Business owners with comparable performance records go bust. Brokers lose their clients. Physicians get sued for malpractice. Yet think-tankers and policy wonks continue to opine, never pausing to reflect on-or apologize for-their spotty records.

You know, we live in a country where if you want to go bomb somebody, there's remarkably little discussion about how much it might cost, even though the costs almost inevitably end up being orders of magnitude larger than anybody projected at the outcome.

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.
