Without public debate and without congressional hearings, a segment of the Pentagon and fellow travelers have embraced a doctrine known as the Long War, which projects an arc of instability" caused by insurgent groups from Europe to South Asia that will last between 50 and 80 years. According to one of its architects, Iraq, Afghanistan and Pakistan are just "small wars in the midst of a big one." Consider the audacity of such an idea. An 80-year undeclared war would entangle 20 future presidential terms stretching far into the future of voters not yet born. The American death toll in Iraq and Afghanistan now approaches 5,000, with the number of wounded a multiple many times greater. And if the American armed forces are stretched thin today, try to conceive of seven more decades of combat. The costs are unimaginable too. According to economists Joseph E. Stiglitz and Linda Bilmes, Iraq alone will be a $3-trillion war. Those costs, and the other deficit spending of recent years, yield "virtually no room for new domestic initiatives for Mr. Obama or his successors," according to a New York Times budget analysis in February. Continued deficit financing for the Long War will rob today's younger generation of resources for their future.
