In March 2003, the United States led an invasion of Iraq that would topple Saddam Hussein's regime, but would have far-reaching consequences for the next two decades. No-one knows exactly how many Iraqis have died as a result of the war. Estimates are all in the hundreds of thousands. The political instability that followed saw the rise of jihadist extremists including Islamic State. There was a civil war and the spread of violent sectarianism across the region. Host James Reynolds brings together Iraqis to share how trauma continues to impact their lives.
