Madu u must understand that American pull out will create a vacuum which many elements of Afghan society would like to fill. According to my view American pull out will create pressure on Talibans as well bcs now they r recruiting the Afghan people on the slogan of " Join the Jihad against Infidels". And when there will not be any infidel in the country then how will they acquire the public support. An other thing u must understand and keep in ur mind that this is not 90s when the people have very few ways of communication. Now, people r connected with each other and the new generation of Afghans have tasted the taste of international t.v channels and have indulged in watching movies and listening songs. They have there own t.v channel as well(Shamshad tv Afghanistan) which is promoting a soft image of Afghanistan in the world. So, in this scenario i dont think that the Talibans will be able to hold sway upon Afghanista. Moreover, when there is no more America in Afghanistan then whose name will they sell to buy the support of local Pakistani people and how will they justify their attacks upon Pakistan. Furthermore, now, due to internet and video clipping they will not be able to cut the Afghan society from the whole of the world and if they will try to do so the native Afghan people will up against them to defend their cultural bounds. (Sense of nationalism and loyalty towards their culture is enhancing very rapidly among the local Afghans and u can see it on their channel)
