Showing destructed city of Aleppo in the videos is seriously offensive to all those innocent civilian who have died in the bloody mass slaughtering started by non other then the west herself.
Why not BBC start the documentary from the point before America and England invaded the beautiful Iraq on wrong accusations which eventually lead to the creation of ISIS.
Why not America and British are being mocked in the video who are the greatest terrorist in Iraqi state of affairs and forefather of ISIS for that matter.
