This may give some perspective to the story that the Russian ambassador laid out the American plan for invasion. Saddam was convinced we wouldn't do it. The Russians attempted to make him understand that, yes, we would.
They showed him what he was up against, only falsifying the start date. This may have been a part of our misinformation. We launched a week before we told the Russians we would launch. I could well be wrong, but I'm asking myself if the leak to the Russians wasn't an official leak, intended to give Saddam a final chance to step aside. We were trying to get him to retire to Belarus or someplace in the final days, but he didn't think we were serious.
It's fascinating, really, to consider your theory.
You seem to be saying that, sure, someone gave dear ol' Saddam all of our plans for the invasion, including strength force, military capability, the number and kind of aircraft, tanks, etc, etc, but it's somehow evident that it's no big deal since whoever did this was off by a week as to the invasion date.
This counts as "disinformation" in your book, in other words?
