"Certain aspects of the Iran-Iraq conflict — including trench warfare, barbed-wire fences and soldiers attacking machine-gun emplacements across open ground — echoed the fighting of the First World War.

No less horrific was Saddam’s profligate use of chemical weapons against the advancing Iranian troops. The conflict settled into a war of attrition. By the time a ceasefire was agreed, in July 1988, both sides were effectively back where they had begun — with over a million lives lost."
