We know the U.S. is at war in Iraq and Afghanistan. What many don't know is a secret war in Pakistan has been waged over the last decade - by the CIA. In lawless, tribal lands the CIA is fusing its expertise in technology and intelligence to hunt down al-Qaeda and Taliban militants. Taking out terrorists and forcing militants out of tribal regions, drone strikes have become an efficient tool.
Next, to bin Laden, the most wanted terrorist associated with 9/11 was Khalid Sheik Mohammed or KSM. He managed to elude the CIA for a decade, and even on the run, he carried out attacks on U.S. and Western interests in Bali, Yemen and Africa.
