Musharraf is lying through his teeth (a common Pakistani trait). Much of the impetus given to fanatical Islam began when General Muhammad Zia al-Haq led a military coup that threw out the Bhutto government in 1977. He filled the military with Islamists, funded thousands of Islamist madrassas, and allowed the schools to teach military training. Within a year of the Soviet invasion of Afghanistan in December 1979, Al-Haq was working with Saudi Arabia to send thousands of Afghan-Arabs to fight in Afghanistan; he allowed more than 100,000 Pakistani jihadists to do likewise. He introduced terrorism into Kashmir and gave the military assignment to -- you guessed it -- Musharraf who had joined the army in 1964 and served with no particular distinction until being picked by Al-Haq to raise hell with India. Al Haq was responsible for arming the Hizb-e Islam and set up a likeminded Islamist movement in the Harakat al-Jihadi Islami which Musharraf helped train. The USA did not really jump into this fray until Reagan was elected and in 1983, at CIA's Casey prompting began to fund the mujahideen. After that, the CIA served as paymaster, not drill sergeant for the anti-Soviet affair. The training of mujahideen who later joined the Al Qaeda was a Pakistani affair, of which Musharraf is perfectly aware. This self-serving bit of twaddle is what one can expect of a South Asian Muslim leader.
Although this history does suggest that, knowing what we know now about islamic extremists, we might have backed the wrong side of the war, and Russia may have had good reason to attack Afghanistan.
They were our sworn enemy, but they've had to deal with muslim extremists attacking their country for a lot longer than we have.
