Dexter Filkins, writing for the New York Times:
"Pakistan’s double game has rested on two premises: that the country’s leaders could keep the militants under control and that they could keep the United States sufficiently placated to keep the money and weapons flowing. But what happens when the game spins out of control? What happens when the militants you have been encouraging grow too strong and set their sights on Pakistan itself? What happens when the bluff no longer works?"
