I dont think only Americans can successfully be motivated by revenge, anyone/any country can, and many other countries have been.
I dont think Revenge is the only way to successfully motivates Americans. Americans are motivated by all sorts of things
But sometimes harsh actions create harsh circumstances. And regardless of what is said or portrayed, sometimes Revenge , in some cases, is the best motivation and drive to succeed.
This country is 200 years old. Thats a spec of time in history. Look at the world prior to. Its nothing new....
Alls im saying is,
Trying to forget something or someone of great significance wont make it go away. People love history, history has tragic times, most tragic stories have some sort of satisfactory ending.
The actions of gloating or not gloating on this particular situation will not enrage or de-motify anyone in anyway. Hatred by the terrorist was established long before this.
Nothing the World does or doesnt do, will have any impact on weather his followers will view him as a martyr or not.
And blowing this guys head off in a video game, hunting down Americas Most wanted will be very entertaining IMO.
