I met a lot of the senior Taliban, and I asked them precisely [about Mullah Omar]. The most common answer was he is humble. And that was very true. We never had reports of Mullah Omar living luxuriously or making money in large quantities or anything like that.

You have a lot of suspicion from the neighbors of Afghanistan about U.S. intentions. Iran is already, to some extent, trying to undermine the U.S. in Afghanistan. Russia is now becoming increasingly nervous about a more permanent U.S. presence in Central Asia. And China is not keen that the U.S. should be so close to its borders over a long period of time. Certainly, if the U.S. is going to be there for a long time, it's going to exacerbate regional tensions.

America does not hold to the colonial tradition. America came, liberated Afghanistan from the Taliban and al-Qaida, came to an arrangement with Hamid Karzai, wanted to organize elections as soon as possible and then withdraw. The Bush administration thought that once there is a democracy, everything else will fall into place. If today you speak to the architects of the 2001 Afghanistan Conference in Bonn, they will tell you that instead of being fixated on elections, we should have built a State in Afghanistan with an army and a police force first.

The Soviets held to the tradition of colonialism. They raped the country and killed many people. But they also built dams, electrical power plants, streets, and technical schools. They were communists and had the same vision for Afghanistan that Stalin and Lenin had for the Soviet Union: Progress is communism plus electrification. And today? Today Kabul gets its electrical power from Uzbekistan, Herat from Iran and Jalalabad from Pakistan.

Some Pakistanis fought for the Taliban. Pakistani extremist groups provided infrastructural support to Al Qaeda. There was a coming and going of Al Qaeda militants and leaders between Afghanistan and Pakistan for several years. All that has really happened is that Al Qaeda has escaped from Afghanistan come into Pakistan, got in touch with their contacts and friends in these extremist groups, which then provided them with safe houses, cars, and not just in the border areas but also in the cities. Rooting out Al Qaeda in Pakistan now is where the main battle is being fought.

The biggest mistake Barack Obama could have made is to change quite a few things in his Afghanistan policy. He increased the number of troops and at the same time set the US withdrawal date to 2014. Now the United States has to ensure that Afghanistan does not immediately collapse after being left to itself in 2014.

I think within a year or so, perhaps, if 9/11 had not happened, in Afghanistan would have been a very broad-based general uprising against the Taliban.
