IS a consequence of Iraq war, says Democratic candidate Martin O’ Malley

Democratic presidential candidate Martin O’Malley says the rise of IS was an unintended consequence of a “mindless rush to war” in Iraq and the US must avoid “mission creep” there now.

In a speech, the former Maryland governor said the invasion of Iraq was one of the most tragic and costly blunders in US history.

He made no mention of his Democratic rival, Hillary Clinton, who faced criticism during her 2008 presidential campaign for her Senate vote in favour of the 2003 invasion, which she has since called a mistake.
