I was reading this and had to register to ask why posters are so defeatist? NATO is not in a good place strategically it has 130000 troops dispersed across Afghanistan, from different nationalities,and without proper resupply if Pakistan mobilizes it's armed forces I'm pretty sure they could quickly overrun the isolated NATO forces and escort them out of Afghanistan.Blitzkrieg NATO would run out of ammunition in days.But it all depends on what the Pakistani military/political leadership decides to do I don't think it would be a one sides confrontation. Certainly Pakistan might suffer heavy causalities in the initial assault but as shown by the Soviets during WW2 and Chinese in the Korean war you could overrun even the most superior firepower through numbers.And again they have no resupply it would be over in a week they would simply have no ammunition left.And the Chinese fought the entire UN not even just NATO and the UN had a lot more forces and proper resupply.Pakistan should think of it's strategic interests the future is in an alliance with China. NATO simply doesn't belong in the region and will eventually leave anyway.Their presence is only temporary.
