National Review has asked me to comment upon the current state of affairs in Afghanistan. I don’t know what the current state is; I do know it doesn’t much matter. Let me explain.
Our reason for invading that remote, medieval country in 2001 was to destroy the al-Qaeda terrorist organization, which had murdered 3,000 civilians at the World Trade Center. Our military failed to destroy AQ but did drive it into Pakistan. To keep AQ from reestablishing a base inside Afghanistan, modest U.S. assets (say, 10,000 troops) are needed.
However, the UN, NATO, and the U.S. decided in 2002 to broaden the Afghan mission to infinite dimensions. The triumvirate determined that 30 million illiterate, fractious tribesmen deserved to be reformed into an economically viable democracy defined by Western values and laws. The West would accomplish this Herculean task while handing total sovereignty over to its hand-picked, “elected” ruler, Hamid Karzai. Unlike the British, who had ruled a century ago via colonialism and reprisals, the West in the 21st century scrupulously abjured direct interference in Afghan affairs, while nonetheless guaranteeing countrywide security, propping up government officials, building an infrastructure, and paying for a viable economy. Once the U.S. established that mission, it could never be ended. Like Detroit or Jersey City, Afghanistan would always need more money.
Throughout the past decade, Pakistan has given sanctuary and aid to the Taliban because Pakistan is determined to keep Afghanistan in a subservient geopolitical position that does not benefit India (or any other power). So by 2006, the American troops in Afghanistan were waging war against the resurgent Taliban. This was not the original mission. And, like the task of ensuring democracy, it guaranteed the U.S. could not leave. Our forces fell under the political control of Karzai, and gradually our generals tightened proscriptions against air strikes to the extent that today, U.S. forces neither patrol nor go out as advisers, while Afghan forces are forbidden to call in air. Fighting rifle against rifle guarantees the Taliban can continue attacking year after year.
