Bill Clinton describes George Stephanopoulos as one of the brightest people on his team during office. It's a classic example of how post rationalisation (Al Qaida had already been blamed) affects all including the most gifted. Take a look for yourself.

You're doing yourself a self a massive injustice if you haven't check out this post by Dr Judy Wood on at least one of the mechanisms used to pull the wool over the eyes of the world so that great acts of evil could be done in the name of faux protection and dramatised fear.
They will try again.
You can count on it, and you can count on it that it will be even more dazzling.
