‘For to win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the acme of skill.’ –Sun Tzu
In thinking about Afghanistan, it is essential that we begin by thinking about the nature of guerrilla warfare against an occupying force. The guerrilla lives in the country. He isn’t going anywhere else, as he has nowhere to go. By contrast, the foreigner has a place to which he can return. This is the core weakness of the occupier and the strength of the guerrilla. The former can leave and in all likelihood, his nation will survive. The guerrilla can’t. And having alternatives undermines the foreigner’s will to fight regardless of the importance of the war to him.
The strategy of the guerrilla is to make the option to withdraw more attractive. In order to do this, his strategic goal is simply to survive and fight on whatever level he can. His patience is built into who he is and what he is fighting for. The occupier’s patience is calculated against the cost of the occupation and its opportunity costs, thus, while troops are committed in this country, what is happening elsewhere?
Tactically, the guerrilla survives by being elusive. He disperses in small groups. He operates in hostile terrain. He denies the enemy intelligence on his location and capabilities. He forms political alliances with civilians who provide him supplies and intelligence on the occupation forces and misleads the occupiers about his own location. The guerrilla uses this intelligence network to decline combat on the enemy’s terms and to strike the enemy when he is least prepared. The guerrilla’s goal is not to seize and hold ground but to survive, evade and strike, imposing casualties on the occupier. Above all, the guerrilla must never form a center of gravity that, if struck, would lead to his defeat. He thus actively avoids anything that could be construed as a decisive contact. (…)
The asymmetry of this warfare favors the guerrilla. This is particularly true when the strategic value of the war to the occupier is ambiguous, where the occupier does not possess sufficient force and patience to systematically overwhelm the guerrillas, and where either political or military constraints prevent operations against sanctuaries.
