I don't think so.
IF the issues are as Podhoretz says, than this only affects the issues regarding the 9-11 Commission (whether or not it supressed the Able Danger information). It does not affect the issues regarding Gorelick's (and Shnell's?) precence in that commission (which blatantly comprimised it, in most of our opinions), and it in no way affects the revelations about The Wall and its part in spiking the investigations that had the 9-11 terrorists on the tips of our fingers a year out.
True, but that wall issue has been there all along and nothing has happened. What IS going to happen? Will there be a call for an investigation into this? I wish, but I doubt it. If this story is proven false, the whole larger story will return to the background.
