An Interesting Quote by David Petraeus From 1987:
“And while observing the Soviet difficulties in Afghanistan with a certain sense of vindication, the US military are at the same time reminded of the difficulties of defeating a determined guerrilla opponent who enjoys sanctuaries and is fighting in rugged terrain. After all, if a country with relatively few public opinion concerns or moral compunctions about its tactics cannot beat a bunch of ill-equipped Afghan tribesmen, what does that say about the ability of the United States — with its domestic constraints, statutory limitations, moral inhibition, and zealous investigative reporters — to carry out a successful action against a guerrilla force?”
