Stephen Biddle’s recent piece on Afghanistan seeks to probe the question asked in the title, Is It Worth It? Biddle’s answer is a tepid, tentative "yes." In his words, our ongoing military campaign in Afghanistan represents "a war effort that is costly, risky and worth waging—but only barely so."
As suggested, Biddle is certainly no optimist about our prospects for "victory" in Afghanistan – although, to his credit, he narrows down the criteria to two modest goals when compared to some of the other more grandiose designs associated with the mission since its inception.
The United States has two primary national interests in this conflict: that Afghanistan never again become a haven for terrorism against the United States, and that chaos in Afghanistan not destabilize its neighbors, especially Pakistan. Neither interest can be dismissed, but both have limits as casus belli.
Biddle quickly abandons the first rationale, however, describing it as the "weakest" reason to wage a war considering the fact that: (a) there is no guarantee that the Taliban would welcome al-Qaeda back if the US departs and the Taliban dominates; (b) we can disrupt so-called safe-havens by taking measures far short of all out war; and (c) there are more attractive safe havens available in several other settings, and waging war to shut them down as they crop up is unrealistic in the extreme (also: a key part of Osama Bin Laden’s strategy of bleeding our resources by goading us into costly campaigns across the globe) – arguments that this site has been making with some frequency.
Which leaves us with the second rationale alone, about which Biddle has this to say:
