No, the Bush administration did not lie about Iraq having WoMD. Out intelligence agencies were fully convinced they had them as the USA Today article I'm linking to shows.
Where you and I are in (likely) agreement is this war never should have been waged. I am against starting a war against a country on what they potentially maybe might perhaps possibly do someday, which was the Bush administration's justification.
4,300 dead and 10,000 maimed-for-life US service members later, we got a completely destabilized Middle East along with 100,000 dead Iraqi civilians, and it only cost us $2 trillion for the privilege. You guys think Donald Trump is the worst president in modern history? Not even close to the damage W did. Trump's a piker compared to George W. Bush.
