Season 1 of The Fault Line: Bush, Blair and Iraq, is also available to view on this platform. On September 11th 2001, as he faced incalculable losses after the terrorist attacks that day, President George W Bush made a call to his greatest international ally: British Prime Minister Tony Blair. 18 months later, Bush and Blair led a coalition into a war that went horribly wrong. David Dimbleby, one of the BBC’s best known news hosts and reporters, takes us back to those crucial 18 months. Talking to prime ministers, politicians, spies and weapons inspectors he asks how and why we came to invade Iraq. And as we experience an era of lies and mistrust – did the events of 17 years ago set the stage for the world we live in now?
