Why?
9/11 was a joint Saudi-Pakistan operation, Taliban had nothing to do with it, don't care at all about it, they have their own country to take back from the Americans and run it how they see fit.
They will celebrate soon enough, but 9/11 for them is just another day on the calendar.
Disagreed. The Taliban gave safe haven to OBL in the lead up to 9/11. 9/11 was celebrated in a lot of muslim countries outside of SA and Pakistan.
