The Iraq National Museum reopened on 28 February. Many of the treasures of ancient Mesopotamia are in the British Museum or the Pergamon in Berlin, or were lost to looting after the 2003 invasion, but some wonderful objects are now on show in Baghdad. I visited last week. As I was looking at pieces of Iraq’s great civilisations in glass cases, the extremists of Daesh (as the Islamic State is known in Arabic) were smashing up the original sites for being idolatrous.
