Shortly before handing over the presidency to Barack Obama, George W. Bush did a farewell tour of Iraq in December 2008. It was supposed to be — despite his 24 percent approval rating — a kind of victory lap, culminating in a press event with Iraq’s new leader, Nouri al-Maliki. But things didn’t go as intended. Muntadhar al-Zaidi, an Iraqi journalist who was furious about the American invasion and occupation of his country, decided to throw his shoes at the American president as a pointed act of protest. Bush ducked both of them — you probably have seen the video — and al-Zaidi was swarmed by security and badly beaten. Later, he endured torture at the hands of Iraqi authorities and was sentenced to three years in prison. It was a small act by one person, but it caught the world’s attention and inspired a great many copycat protests. Fifteen years to the day after the shoe throwing, this oral history by writer Jordan Heller looks back at that moment, through the eyes of al-Zaidi and others who were there, and seeks to do an accounting of its importance and its consequences.
