Can the US and Pakistan Mend an Uneasy Alliance

Pakistan is crucial to US interests, with a growing nuclear arsenal and a strategic location, but ties to anti-American terrorists and political unrest have strained relations. After 60% of the voters braved deadly violence, Prime Minister Nawaz Sharif's party won big enough to raise hopes for stability. Yesterday at the White House, he called for an end to American drone strikes, but leaked CIA files detail how deeply Pakistan’s military has been involved in drone strikes — even helping to choose targets hundreds of times. The files also describe "tense meetings" with US officials accusing Pakistan’s intelligence service of ties to militant groups that attacked American forces. What's the state of Sharif's credibility? Does either country trust the other? Can diplomatic and economic relations be improved?
