While speaking at an event at the George W. Bush Presidential Center that examined the future of American elections, U.S. president George W Bush made a significant slip while criticizing Russian President Vladimir Putin.

"The decision of one man to launch a wholly unjustified and brutal invasion of Iraq" Bush said before correcting himself. "I mean of Ukraine. Iraq too, anyway."

Bush was referring to the U.S. led invasion of Iraq during his presidency. Reports during that time of chemical and biological weapons, including weapons of mass destructions were used to justify the invasion, however, a closer examination produced negative results.
