‘There is no military solution to Afghanistan’
You may be right, but the statement is most likely true. Afghanistan has been the graveyard of empires for 2000 years. There are no natural resources or strategic reason to be there other than to prevent it from being a launching pad against Western countries. The way to keep that from happening is cut deals with the tribal leaders even if you have to pay them off. Afghanistan is the size of Texas and 30,000 or 60,000 troops are not going to be able to secure all the tribal regions and the border with Pakistan.
