The assassination of Benazir Bhutto could end up being the most devastating act of terrorism since the assassination of the Arch Duke Ferdinand triggered World War 1 in 1914. A great deal rests on how the US Govt handles this matter. As they did in 1914, a serious of events could follow this assassination that might trigger a regional, possibly nuclear, war.
IMO it is overstating the situation. Lots of hyperbole. The military will step in if things look like they are getting out of hand.
