What did Musharraf know and when did he know it
It is entirely plausible that Pakistani intelligence knew about the 9/11 plot given its deep links to both the al Qaeda and the Taliban. The chief of the ISI at that time, Lt Gen Mehmood Ahmed was one of the instigators of the coup that brought Musharraf to power. As army chief and president, Musharraf presided over the military-intelligence apparatus that was ‘handling’ the Taliban and the al Qaeda. This is quite substantial circumstantial evidence, enough to implicate him personally. Saddam Hussein was attacked for less.
B Raman argues that it is inconceivable that Musharraf did not know about the attacks, or at least the possibility of it. Yet, he did nothing to warn the United States about them. This is yet another crime for which the General is escaping being called to account.
