The Ghost of Osama bin Laden also keeps on emerging from his grave/grave to come and deliver the messages at the hour of need that United States wants it the most. These messages in turn grant a new life to Terrorism and mark it that purported Al-Qaeda Terrorism is live and kicking as ever.
This is very conveniently used as the pretext and an enabler that United States has very successfully evolved to exterminate any opposition in the way in the name of elimination of Terrorism. Al Qaeda and its Terrorism have proved to be the umbilical cords for US, so called moral grounds to maintain her presence in occupied foreign lands in and around of Iraq and Afghanistan.
US is now eagerly looking ahead and waiting in the wings to invade their next planned ultimate target - Pakistan. Thanks to our ever present (dead or alive) Muslim friend Osama bin Laden!
