It’s all unnamed sources and circumstantial, but it’s also very tightly woven threads that line up very clearly. Think of this like the initial reports about how Iraq 2 WMD stuff was all made up by the Bush Admin. There wasn’t hard evidence, but the manipulation was pretty easy to connect the dots on at the time. I doubt he can put names to sources without folks getting suicided, but it’s very solid analysis of how all the puzzle pieces fit together by a respected journo that has consistently been correct when doing these types of exposes.

It’s not proof. Really, without named sources and evidence it might as well be political fiction. But there’s also no one else who had both the means to do it and the motive to do it other than America. Every other party that would benefit couldn’t have pulled it off, and of the parties who could have pulled it off it really is just the US and maybe, maybe someone like Norway if they had their best commandos and their best oil rig divers work together?
