Actually to give you a more obviously intelligent reply, let me say that I believe Russia's position is driven purely by their terrible economic mess and the financial realities of siding with the U.S. being a minus for them in the short run, which is the only run that matters to most politicians when your voters are in dire economic straights. This decision is not that hard as they have been long allies with Iraq and until recently were enemies with U.S. This is hard decision for Putin, as he wants to throw Russia's fate in with the West, but he is deciding "It's the economy, stupid." for the short run.
China may be an unseen hand in 9-11, one of several, including Saddam, that supported very covertly al Qaeda's terrorist attacks. And they have all the obvious motives.
The question remains if Jacques Chirac, lusting for EU primacy, may have given the nod to more than he realized and is now trying to cover his tracks.
I hope your analysis is correct and not mine. I'd prepare for mine to be right, though, were I a defense planner.
