There is clearly a lot of anti-American sentiment in Pakistan, less so in Afghanistan, but I think that this will feed into it.

More than a decade and half after 9/11, U.S. military actions in countries such as Syria, Iraq and Afghanistan and several other Muslim nations are governed by the Authorization for the Use of Military Force (AUMF) that was passed in the days immediately after 9/11.

The documentary feature film 'Legion of Brothers' tells the stories of the handful of U.S. Special Forces soldiers who, shortly after the 9/11 attacks, went into Taliban-controlled Afghanistan and, within a matter of weeks, overthrew the Taliban regime.

In mid-November 2001, as they moved toward the city of Kandahar, the Taliban's de facto capital in southern Afghanistan, Amerine's team called in airstrikes against advancing Taliban units and more or less obliterated a Taliban column of a thousand men that had been dispatched from Kandahar. It was the Taliban's final play to remain in power.

What bin Laden had hoped to achieve in Afghanistan in the post-9/11 period, which was to drag the United States into a protracted guerrilla war like the one he had fought against the Soviets, never happened. Instead, that protracted guerrilla war is now playing out in Iraq, in the heart of the Middle East.

The 9/11 attack itself played out around the world, with planning meetings in Malaysia, operatives taking flight lessons in the United States, coordination by plot leaders based in Hamburg, and money transfers from Dubai - activities overseen by al-Qaeda's senior command from secure bases in Afghanistan.
