Here we are assuming that Osama did have full administrative authority over those who were on the airplanes. Which I don't think anyone of us know. However, my belief is that even though his business dealings with the US in the past may have provoked the "alleged" retaliation. That violence will never do anything but make the world a worse place to live while negatively impacting the global economy. Anyone can dream of making the world a better place. but it takes a psychopath to orchestrate flying planes into building's.
