The UK is signing on to a half-century old provision from the Hague convention’s rules of war which allows for the protection of cultural treasures from marauding armies. British politicians had always dismissed the guidelines, which call for labeling specific works of great cultural or artistic significance with a blue shield, but reconsidered after the 2003 looting of Baghdad’s museum in the wake of the American invasion. Now the government is launching a consultation process to determine the works of art that should be selected for the special treatment.
