Destroying Mosul in order to save it

The Islamic State is mostly gone from the ancient city of Mosul after what some veterans call "the toughest urban warfare since World War II." Iraq's Prime Minister Haider al-Abadi has declared victory, but half his second largest city is in ruins. Thousands are dead; more than 700,000 are refugees. Nobody thinks peace is at hand — while ISIS still holds the Syrian city of Raqqa and fosters violence in other places, too. Will the US and other western countries help rebuild Mosul — while Kurds, Turks and other factions struggle for power?
