Taliban leader Dadullah claims that Bin Laden planned the Feb attack on Dick Cheney in Afghanistan

I don't believe it at all.

For Bin Laden to plan such a coordinated, complicated, and timely attack like the one targeting vice president Dick Cheney he would have to be active and out in the field. He would need to be commanding things and meeting with different people. That's certainly not the case. Bin Laden is deep in hiding and most likely spending most of his time trying to avoid capture. We haven't heard from the guy in over a year! He definitely wouldn't put himself out there like this. The only reason the Taliban is giving him the credit is so he can stay relevant. They want to try to show that he is still very much in charge and aware of the day to day activity of the global jihadist movement. When in reality, he is probably cut out from the outside world hiding out in the basement of some crappy safehouse in a village in northwestern Pakistan.
