Who is silly enough to believe there will be a military victory in Afghanistan?

I feel very pessimistic about the Afghan situation - I don't think NATO can win. For one thing their lines of supply are very exposed. What happens if Pakistan disintegrates or Russia becomes obstructive ? The Soviets had total control of their supply lines into Afghanistan through which they poured mes of men and material only to loose in the end. The British troops have fought well often with woeful equipment and support. The Canadians have been great but where are the Germans,French and Italians ? The Taliban are formidable fighters in extremely rugged terrain - the situation is much different from Iraq.
