It is time for the USA to "abandon" Pakistan, once again. Let China and Russia nurture Pakistan. After all if Pakistan held a plebiscite about whether or not the USA should leave Afghanistan and Pakistan, the vote would be overwhelmingly: YES!!!!
So, let the people's will (in both the USA and in Pakistan) prevail.
If terrorist attacks then occur on American soil that have been supported by groups sheltered in Pakistan, then Pakistanis will not mind being collateral damage. It's their free choice, after all. They will have chosen to throw their lot in with such groups. Maybe Allah will reward all who perish.
The US has been committing acts of terror on Pakistani and Afghani soil on an almost daily basis for a while, with drone attacks, bombing weddings, and funerals, killing men, women, children, elderly etc. That region has a code that predates most religions, if you kill one of their family members, they will kill one of yours or die trying. If you want peace in the world, stop creating enemies.
It's probably no coincidence that the Soviet Union collapsed more rapidly after their failure in Afghanistan, and the US is following the same path by going trillions into debt on foreign entanglements, while their economy is in the worst shape since The Great Depression.
Interesting that people who rely on mules and live in caves have essentially bested two of the world's most formidable superpowers.
