As savvy analysts told me at the time, the split likely marks a return to Pakistan’s discredited policy of Good Taliban; Bad Taliban. While American troops head home from Afghanistan, while an election is under way, it would be silly of Islamabad to give up its proxies, runs the reasoning. Who knows what might happen across the border? Who knows what allies Pakistan might need? So long as the Good Taliban steer clear of Pakistani targets then all is well. Rather than clear the militants, the havens can be left for now.
