British Envoy says Mission in Afghanistan Is Doomed, According to Leaked Memo

The official version of the US-led campaign in Afghanistan received a blow today with a leaked report that the British Ambassador in Kabul believes that US strategy is wrong and the war is as good as lost.
"The current situation is bad. The security situation is getting worse. So is corruption and the Government has lost all trust. Our public statements should not delude us over the fact that the insurrection, while incapable of winning a military victory, nevertheless has the capacity to make life increasingly difficult, including in the capital. "The presence - especially the military presence - of the coalition is part of the problem, not the solution. The foreign forces are ensuring the survival of a regime which would collapse without them. In doing so, they are slowing down and complicating an eventual exit from the crisis (which, moreover, will probably be dramatic)."

Who really wins a war besides the arms makers and coffin builders?
