The most expensive public enemy in American history died Sunday from two bullets.
As we mark Osama bin Laden's death, what's striking is how much he cost our nation—and how little we've gained from our fight against him. By conservative estimates, bin Laden cost the United States at least $3 trillion over the past 15 years, counting the disruptions he wrought on the domestic economy, the wars and heightened security triggered by the terrorist attacks he engineered, and the direct efforts to hunt him down.
What do we have to show for that tab? Two wars that continue to occupy 150,000 troops and tie up a quarter of our defense budget; a bloated homeland-security apparatus that has at times pushed the bounds of civil liberty; soaring oil prices partially attributable to the global war on bin Laden's terrorist network; and a chunk of our mounting national debt, which threatens to hobble the economy unless lawmakers compromise on an unprecedented deficit-reduction deal.
All of that has not given us, at least not yet, anything close to the social or economic advancements produced by the battles against America's costliest past enemies. Defeating the Confederate army brought the end of slavery and a wave of standardization—in railroad gauges and shoe sizes, for example—that paved the way for a truly national economy. Vanquishing Adolf Hitler ended the Great Depression and ushered in a period of booming prosperity and hegemony. Even the massive military escalation that marked the Cold War standoff against Joseph Stalin and his Russian successors produced landmark technological breakthroughs that revolutionized the economy.
