In 2003, the United States invaded Iraq without deciding whether it should. The George W Bush administration failed to ask whether the costs, risks and likely consequences of regime change justified the gamble. The result was tragedy – for Iraq, for the Middle East and for America.
Donald Trump’s attack on Iran now follows the same pattern – but with an even narrower logic of performative power. In the run-up to Iraq, Washington devoted enormous energy to planning the invasion. Almost no attention was given to the more important question: was war necessary, and could it realistically produce a stable political outcome?
