What is the "Downing Street Memo" anyway?

I have to admit, I have no idea. I will be reading these sites to find out. It sure sounds official and serious though, doesn't it? It really requires our knowledge and awareness, so we can inform others. Thank God for Cindy Sheehan and her supporters for helping America to start out shouting "The emperor isn't wearing any clothes!"

Here are a couple of sites to look at:

• The letter to Bush with some specific questions about the situation. It seems as if the Memo itself is the "smoking gun" which shows that Bush had intended on attacking Iraq long before he was supposed to. This letter briefly summarizes the history and the questions we expect Bush to answer. You can sign it and send it to Bush from this site as well.
• Brits and Yanks Unite to Demand Answers to Downing Street Minutes
• Coalition of citizen groups seek formal inquiry into whether Bush acted illegally in push for Iraq war
