That story came from Niaz Naik, a Pakistani diplomat. Naik also asserted that Uzbekistan was to participate in the operation and that 17,000 Russian troops were on standby to aid the invasion.
http://news.bbc.co.uk/2/hi/south_asia/1550366.stmhttp://www.globalpolicy.org/wtc/analysis/2002/0816salon.htmObviously there's no evidence to support that. If anything, Russia has grown concerned about military operations beneath its southern border and there's no evidence that Russia played any role in the invasion of Afghanistan that actually occurred in 2001. Naik's story is very clearly an exaggeration. Ahmed Rashid has argued that Naik was trying to exert pressure within the Pakistani government and so deliberately exaggerated. That at least is consistent with the fact that we have no reason to believe that 17,000 Russian troops were standing by to aid the invasion of Afghanistan. Given the clear exaggerations and the plausible motives for Naik as someone trying to push the Pakistani government to break its ties with the Taliban, the whole story seems doubtful. Even according to Naik's version of the story taken on faith, the conditions required had nothing to do with a pipeline but were rather demands that Bin Laden be turned over. Of course, there hasn't been any indication of a pipeline being set up in Afghanistan.
Regardless of that, however, it has no bearing on the original point which you had claimed to be responding to. Maybe someone will eventually find some corroborating evidence to support Naik's assertion and maybe not. But either way, we know that the Bush administration was not acting with "good faith" when they tried to pin the blame for 911 on Saddam Hussein. However arguments about the "good faith" of the Bush administration are a strawman as far any claims for a conspiracy are concerned. To substantiate a conspiracy you need more precise arguments than simply the fact that the Bush administration acted in bad faith. Your citation of Naik's story is indicative of exactly the errors one must be cautious of the moment we step beyond charging the Bush administration with bad faith and attempt to construct a conspiracy theory.
