Americans once believed that their prosperity and way of life depended on having assured access to Persian Gulf oil. Today, that is no longer the case. The United States is once more an oil exporter. Available and accessible reserves of oil and natural gas in North America are far greater than was once believed. Yet the assumption that the Persian Gulf still qualifies as crucial to American national security persists in Washington. Why?

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?

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.

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?

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

As a kid I was enamored with fiction, most of it utterly forgettable and long forgotten.

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?
