Having the Indian army lay waste to the entire dismal affair hardly seems like a worse outcome than the status quo.
I don't think we're disagreeing. Salafist penetration of the government and the ISI has pretty well consigned the whole country, and the Abbottabad affair pretty much tied a ribbon around our impending hostilities, damn near guaranteed now.
Now ..... how to skin this cat? And how to keep the Chinese from effectively interfering? I think the Himalayas will be a big help, even though they've held the passes for 45 years in adverse possession; and if need be we can whip the PLA in the passes and valleys if they try to get into Afghanistan and Pakistan from the east.
We'll want to detach Baluchistan and run a supply line to Afghanistan through there ..... and if a couple of Paki burgs have to fall under the hammer, so be it; we can't have wild-eyed Wahhabists in our rear areas and threatening our supply lines and flanks. Bang, you're dead, maximum casualties, drive the population out. No more Mr. Nice Guy, they screwed us and were planning to screw us some more.
