Just in case politicians of the future suggest to invade Afghanistan to establish whatever will be the reasoning for military intervention then.

Excellent research. Should be read and well understood by all politicians of the countries involved in Afghanistan! They should also remember George Santayana's Statement that "Those who do not remember the past are bound to repeat its mistakes"!
