For the past two months, President Barack Obama has been weighing Gen. Stanley McChrystal’s request to send an additional 40,000 troops to Afghanistan to “disrupt, dismantle and defeat” al-Qaeda. That same effort, according to Obama, entails ensuring that the Taliban can’t regain control of the country. But a military strategy alone won’t beat al-Qaeda or the Taliban. Achieving lasting stability in Afghanistan will require national political reconciliation, the establishment of a functioning, accountable political system, and a credible government. In this respect, the outcome of Afghanistan’s presidential election, marred by cheating, was a step in the wrong direction.
