Before jumping into any conclusion one has to understand how the ISI operates. In Pakistan, unlike India, we know that the military was always more powerful than the govt itself. So is the case of ISI. It's operation may not be sanctioned by the govt itself. In no way the govt can bridle ISI. In the US once upon a time CIA was more powerful than the President itself.Only after Hoover's death CIA could be brought under control. It could have been better said that ISI was behind the attack.
