This talk explores the impact of the US-led invasion of Iraq in 2003 on militant Islamism using new evidence.
How did the US-led invasion of Iraq in 2003 affect the evolution of the transnational jihadi movement? The consensus view since the mid-2000s has been that the war fuelled militant Islamism, but there have since been few attempts to specify the effects and identify the mechanisms involved. In this talk I draw on a wide range of unexploited quantitative and qualitative evidence to understand the war's impact on transnational militancy. I find that the detrimental effects were even larger than previously assumed, and I make the case, through counterfactual analysis, that jihadism as a transnational movement could have largely fizzled out in the late 2000s had the Iraq war not occurred.
