It’s very simple !
American army instead of fighting the taliban in Afghanistan is just sitting in the camps distributing arms to Afghan army which is not organised/reliable at all. A lot of these arms end up in the hands of Afghani/Pakistani taliban eventually. Things would be much different if American forces were able to control Afghanistan after 9 years of occupation.
Our army is fighting these talibans head on inspite of heavy casualty they are facing on daily basis. Their task has become much more difficult because Pakistani taliban are getting regular supplies via Afghanistan due to lack of control there.
Instead of regular advice to Pakistanis in an open Paksitani forum you will use your historical and technical expertise much more effectively if you start posting in an open American forum advising them to control Afghanistan by suggesting the American army to come out of their camps and fight these talibans themselves instead of relying on Afghanistan army. You should not forget to advise them on ratios and numbers… as they are as important in Afghanistan as they are in Paksitan !!!
