Blaming the US for the problems is like blaming your parents (or whoever paid for college) for the way you turned out. It is true. But it does not provide a useful solution.
The US used Zia to pump more fundamentalism in Pakistan to use against the Soviets (no different than the Brits using desi troops to fight the independence movement. Desis everywhere are the same.)
It is true that the same fundamentalism has come to hurt the US. But Zia used that so called Jehad to screw India and Afghanistan after the US left and in the process screwed Pakistan also. That was NOT the US choice.
Pakistan should use this opportunity to destroy Zia's legacy and become a secular state. Unfortunately, with weapons of this type provided, they will just make the army stronger, give them the means to attack India and distract Pakistanis from the real problems.
