Osama bin Laden is dead and al-Qaeda has suffered a major setback but the complete destruction of al-Qaeda is not attainable -- you cannot destroy an idea that people believe in.

I really doubt any "lesson" has been learned by either side here.
There is no clear victory to be had and there never was.
