they were here to grip on asia as ahole and take revange from islamists and common muslims . but as other side islamists have huge manpower on the name pr jannat and shahadat it was not possible to hold the ground easily . the war of afghanistan was turned jehad long ago by CIA /ISI and this part of world so many crazy people ready to kill and die on the name of religion . USA failed because they were fighting with people whom willing to die for religion and willing to kill for religion but can not live with religion . good example taliban used drug money to fight a war .
i think leadership of terrorist groups like af/pak taliban AQ ISIS laughing on word jehad every time they hear it
