Let's break this into nice bullets

  • Pakistan has nukes
  • Pakistan is key to NATO strat. in Astan
  • Pakistan has given key intel in the past that has been VERY helpful
BUT

  • Clearly they are at least playing both sides'
  • Here and SA are where the real problems are but they of course pose their own very uniuqe set of issues
Now I don't care we violated their sovrigenty, certain perks come with being a superpower and occasionaly breaking down the door is one them.
For me #1 priority is making sure the nukes are safe and this supercedes all other concerns
