How do you measure success?
You are either right, or you're not.
9/11 happened because of a failure to communicate all the dots, let alone connect em.
As for Iraq/WMD, how many times was it pointed out here that "They are keeping info hidden".
"They know so much more than we do". "
Thay're intelligence is good enough to go to war on."
"They need to keep their resources hidden"
"They cant reveal information because it would endanger their sources"
"We know where they are"* ??????
And as was pointed out in return, all weapons-grade BS.
*destined to go down in history as an all time classic blooper.
