Perhaps a good crash course in comprehension & angreji would be of great help. BTW there is tons of material on US and its “tail between the legs” startegy or what they say in your world the great “exit strategy” A strategy that is usually devised after success but not in this case, Does Vietnam/NoKo rings the bell?
May be you should take a crash course in HISTORY too along with other two mentioned above to understand in what context “Those who do not learn from histroy are doomed to repeat it” is quoted when they talk about Afganistan.
Here try this, it may help, there is plenty more where that came from just ask.
P.S: I do not blame the mods to delete your rebuttal which I am sure as usual was nothing more then noise and waste of bandwidth.
