Sy Hersh broke the Abu-Ghrab story.
You said he wasnt credible. If Sy Hersh's Abu-Ghrab story was credible, isnt it then plausible that his story about Bush supporting terrorists is credible.
You seem to be saying that because the story is being reported by Hersh, that you dont believe it.
If someone had told me that in 1979 we were selling Iran weapons to illegally arm rebels in Central America, I probably wouldnt have believed it.
If left with the choice to trust the credibility of Sy Hersh vs George Bush, I think the choice pretty clear.
