Did our intelligence agencies miss that?
Not likely.
The quote you used was not from me but from post #138 by End Times Crusader.
I challenge anyone to prove that Iraq moved their WMDs to Syria before the US invasion of March, 2003. Reciting the number of trucks in a convoy, as enticing as that may be for conspiracy theorists, does not constitute proof. (I recall, in years past, similar conjecture about Ryder trucks parked at an Army base near Oklahoma City.)
My intent was to point out that when the official story gets in the way of what we want to believe, it's often an easy task to devise alternatives that are believable to like-minded individuals. This is not to say the official story is always true or always false, only that a better attempt must be made to produce all-inclusive reports if the government hopes to regain credibility in this Internet age.
Sorry, I forgot the /S tag on my previous post #129.
