Wow.... you have no idea what's going on.. If US didn't want there would be no elections in PAk. No sharif ofcourse. People politics in Pak dosnt bother anyone. Any dictator/pm/president/sardar/don/general/mawali/goonda who heads pak is an automatic ally of US not because of stability but simply because pakistani's love US. US doesnt need the consent of anyone to sell arms in pak/balochista/pakhtoon/fghanistan..whatever is oing on in Pak is absolutely pakistani..nobody is interested in Pak right now...
