A few days after Barack Obama's December 2009 announcement of 33,000 more troops being sent to Afghanistan, in testimony before the Senate Armed Services Committee, Defense Secretary Robert Gates advanced the official justification for escalation: the Afghan Taliban would not abandon its ties with al-Qaeda unless forced to do so by US military force and the realization that "they're likely to lose."
Gates claimed to see an "unholy alliance" of the Afghan Taliban, al-Qaeda and the Pakistani Taliban emerging during 2009. Unless the United States succeeded in weakening the Taliban in Afghanistan, al-Qaeda would have safe haven in Afghanistan, just as they had before the 9/11 attacks, according to Gates.
Even in comparison with the usual lies that justify wars, this one was a whopper. Gates was deliberately ignoring the serious political split that had become apparent in 2008 between Mullah Omar, the spiritual and political leader of the Taliban, and the leadership of al-Qaeda over fundamental issues of strategy and ideology.
After the July 2007 Pakistani military assault on the militants occupying the Red Mosque in Islamabad, al-Qaeda had openly backed Pakistani militants in their declaration of war against the Pakistani military and the Pervez Musharraf regime.
Omar, who needed Pakistani support against the US-NATO forces, began urging Pakistani militants to shun violence against the Pakistani security apparatus, but the newly established militant organization Tehrik-e-Taliban paid no attention to him, as recounted by the recently murdered Pakistani journalist Sayed Saleem Shahzad in a book published just days before his death.
