Contrary to popular perception, al-Qaeda is not necessarily against free elections. And elections in Pakistan – without Musharraf's interference – may fall more overwhelmingly in favor of radical Islamists than many suspect. This statement is a gross under-estimation of Pakistani popular support for Islamofascism. Everything I've read since 2001 indicates it's overwhelming but temporarily under Musharraf's lid.
And when Pakistan as we know it falls, it will surely most likely become run by al-Qaeda and/or al-Qaeda aligned Islamists. An Islamist figure such as former ISI (Pakistani military intelligence) Director Hamid Gul can be expected to rise to grasp the official levers of power within Pakistan. A figure such as bin Laden will never publicly hold such official title, as an “al-Qaedastan” would draw too much international ire. Hamid Gul and Aslam Beg have openly called for a Pakistani military and nuclear alliance with the Iranian mullah regime. [The] 'best-case' is one in which Musharraf no longer controls Pakistan and its nuclear arsenal, but a trustworthy General seizes control of at least the nuclear weapons.
