You pulled a Whomod, M E M.
(I.e., posting a link that doesn't support what you are alleging.)
You allege that Bush knew before invading Iraq that the Saddam Hussein didn't have WMD's.
Your article says that two years after the invasion, in 2005, that Bush saw a report reviewing intelligence (not just for Iraq, but intelligence for multiple other nations) and that in retrospect it was an intelligence failure.
Not because "Bush lied", but because 15 different intelligence agencies don't share information. And not because Bush knew in advance. Bush invaded Iraq with the best intelligence available at the time, with what every other nation doing espionage on Iraq believed, with what Iraq's own military leadership believed, and only after Iraq's weapons records and inventory had been seized could it be known that Saddam Hussein was cooking the books and exaggerating his own WMD capability with forged records.
You really ought to work on your reading comprehension.
Or maybe you just want to believe your own propaganda so badly that you just can't process the true facts, even from an article that YOU LINKED !
As myself, G-man, and others here have posted exhaustively over the last 10 years, Saddam Hussein may not have had the numbers of WMD's that were expected on invasion, but there most certainly was a WMD program ready to go into production.
For example (from the WND/Foreign Policy article) plants for chemical weapons, where Saddam would have a paint company and a pesticide company two miles apart from each other, with chemicals that when combined formed Sarin nerve gas.
Or Iraq scientists with deadly germ-warfare bacteria in their home freezers.
As much as you try to evade the truth and smear Bush, these are undeniable facts.
As weapons inspector David Kay affirmed in his testimony before Congress.
