Who is the Hero and who is the Villain?

This was almost like a scene straight out of a Hindi Movie. The Big, strong, all good  American Army chases a bad bad villain Osama Bin Laden and then kills him. All is well that ends well. But is it? Is all well post Osama Bin Laden Killing at the hands of America? Not really. Whom are we fooling. In the first place what I fail to understand is the so strong motivation that America has shown in finding and killing Bin laden. Ten years of hard work, focus and more than 3 trillion dollars in cost. Why was America soooo keen to find him and kill him? Why was the mighty America scared of Osama Bin Laden? Despite boosting of the strongest Military in the World, Osama Bin Laden had shaken America's confidence in their safety and security standards. By striking right in the heartland of America and causing panic amongst the American's, Bin Laden had proven to the World and more so to America; your citizens are as vulnerable to death as people in a poor nation like Pakistan. Osama's terrorist attacks on America was a big big dent in the American pride. The pride had to be restored. And so Bin Laden had to be killed by the heroic American Military. To prove to the world, look no one else could have done it. We are America. The mighty super power in the World. Only we could do it! Well that's all there is to this chase and kill story. And so dear O (b) ama.....I am not impressed with the heroics of America. Guys, the world would have appreciated you more had this 3 trillion dollar been spent on research for cancer, Aids and other killer diseases striking the developing nations. Honestly other than you Mr. O (b) ama, no one cares a damn if Mr. O (s) ama is dead or alive!!!!!!
