You just need to wake up from your delusions.
When US diplomats meet your favorite politician there is nothing wrong, but should they meet (it is their actual job, BTW) other politicians, then it is a grand conspiracy. How is this supposed to work? Is your bias the sole arbiter here or what?
You don't need memory loss. You just need a dose of reality to wake you up from your delusions.
Here, read this just so you know how diplomats work:

This is about Robin Raphel who spent much time in Pakistan & had relations with many politicians in Pakistan. Notice how she filed a report about IK's 2014 dharna & correctly predicted that it would fizzle out despite backing from elements within the army? This is how diplomats operate & this is how State Department, MoFA, MoEA, or whatever else you call it in any country uses its diplomats on the ground - to know what is going on in any other country so that they may help that country take correct decisions. Also note that how Robin Raphel was in turn targeted by Homeland Security for having contacts in Pakistan on suspicion of being an agent for Pakistan's government. So all it takes is a nutcase to make a bad case (in your case it is IK) & to show you a conspiracy where people are just being themselves & doing their jobs.
PDM is victorious. Mostly likely these people will go on to make the next government. It is important for Pakistan that they are able to deal with American diplomats & it is equally important for American diplomats to know who to talk to & what is important to them. This is how diplomacy works. This is how formal & informal channels work. I know that CIA also works via American diplomats. But that is no reason to shut US embassy & send everyone home. All countries work with diplomats & operatives both in their countries & in other countries. You do not get to have total control just because you are paranoid.
