You have presented a situation where if you refuse their aid, refuse to act against militants, keep shooting their drones and shelter those rogue factions to operate. Their will be more than enough legal ground for USA to do whatever they like. Chinese can't do a thing.
We are fighting our own war and we will do what is in our best interests. We are the ones stuck with the Tallies and we will decide what is best for us. US' duplicity came into light when we tried to fence the border with Afghanistan last week and Kabul opposed it. Why is US silent on this?
What about handing back the Angoor Adda to Afghanistan. It got closed. Afghanistan is blocking every single effort by us and the US keeps silent. Let them go and build a case against Pakistan to attack us. They won't succeed. China, Russia and Germany will never allow it.
War isn't something Pakistan Army or establishment can even think of against the superpower. They will surrender without questioning. You guys speak of corruption that allows US to intervene in Pak while the truth is simple that you can't admit.
War is no option, not for us and certainly not for America. We're talking about Pakistan with tactical nukes, not a weak country like Iraq, Lybia or Afghanistan. G.I. Joe isn't enough to capture the nukes.
Infact, you have surrendered to their terms before as well. You aren't/weren't a US ally in spirit ever. USA calling Pakistan an ally is just an excuse for various complex reasons.
Like I said, it's not the nineties and Pakistan has options. We are slipping away from the US' camp and that's what the Administration is worried about.
