Well personally, someone would have to be thick in the head to fantasies about a scenario like that. But take the latest development across the border:
UK troops to pull out of Sangin - CENTRAL/S. ASIA - Al Jazeera English
Just goes to show how volatile and fluid the situation in Afghanistan still is, it is not as simple as many think. And many of the concerns of Pakistan are totally justified.
If the Americans do loose, who do you think stands to suffer most? I will tell you who, the Afghani and Pakistani people. That’s who!
And they have the audacity to say "Pakistan does not commit enough troops"...
What happens if NATO lose control of Helmand? Where are those guys headed to re-supply and re-arm?
It is clearly evident that Pakistan is faced with a very difficult fight on its hands, its operations in FATA and its continued worries about Taliban influence in Quetta and Baluchistan. To claim that all in Pakistan are having "wet-dreams" of the glorious Taliban destroying the evil goliath that is USA... Well im sorry but that is both naive and far from the truth.
