it is pointed out that 92% of the Afghan people never heard of the events of Sept. 11, 2001.

Immaterial the events of 11th September, 2001 have got nothing to do with the role and presence of ISAF troops in Afghanistan.

If you doubt that then do not please take issue with me for stating that instead read and take it up with the United Nations:

The Bonn Agreement

And

ISAF Mission Statement
