Blair was referring to the claim that Saddam`s regime possessed weapons of mass destruction, which was used by the U.S. and British governments to justify launching the invasion. But the intelligence reports the claim was based on turned out to be false.
The ensuing war and dismantling of Saddam`s government plunged Iraq into chaos, resulting in years of deadly sectarian violence and the rise of al Qaeda in Iraq, a precursor of ISIS. Tens of thousands of Iraqis, more than 4,000 U.S. troops and 179 British service members were killed in the lengthy conflict.
As the most high-profile foreign ally of former U.S. President George W. Bush in the Iraq invasion, Blair has found his legacy overshadowed by the war, with questions and criticism following him wherever he goes.
The consequences of Bush`s decision to to take America into Iraq has repeatedly reared its head this year among candidates vying for the 2016 Republican presidential nomination.
