This film is totally biased- both in part of American efforts and military success and in part of the views of the people of Afghanistan.
One big hole in this film is that it is made based on the accounts Pakistanis and their sympathisers are giving.
Afghanistan is not only Pashtunes land. In this War against the US only tribal Pashtunes with links to Pakistan have participated. There is no Tajik, Uzbik and Hazara fighting against the US.
It is wrong to say Pashtunes dont accept foreign rule. It is 60 years Panjabi are ruling over them. Not only ruling over them but also Pakistanis have made them a proxy army.
The British ruled over Peshawar and other Pashtune areas. It was only the people of Kabul who fought and expelled British from Afghanistan. But Kabulis were and are not Pashtunes.
It was the whole Afghanistan who fought against the Russians and the main fronts against Russians were in the lands of Tajiks, Hazaras and Uzbiks. Pashtunes alse took great part in war aginst Russian invasion. But it was the efforts of the whole nation- all ethnic groups that expelled Russians.
This was against the US is not the war of Tajiks and Uzbiks ane Hazaras. Because these ethnic groups were allied with the US and they had opposed the Taliban in the past.
So, because of so many points this film is biased and under strong influence of Pakistan.
