The U.S. trucking industry has been complaining for years of a shortage of qualified drivers. But skeptics argue the industry is beset by a driver pay shortage and that more people will sign up to become drivers as wages go up.

With Islamic State expelled, Iraqi Christians are trickling back to the ransacked town of Qaraqosh, beset by anxiety for their security and yet hopeful they can live in friendship with Muslims of all persuasions. The town, about 20 km (12 miles) from the battlefront with Islamic State in the northern city of Mosul, shows why Christians have mixed feelings about the future of their ancient community. In the desecrated churches of Qaraqosh, Christians are busy removing graffiti daubed by the Sunni Muslim militants during two and a half years of control - only for new slogans to have appeared, scrawled by Shi'ite members of the Iraqi forces fighting street to street with the jihadists in Mosul. But nearby a shopkeeper is doing a brisk trade selling Dutch beer, Greek ouzo and several whisky brands to Christians, Sunnis, Shi'ites and Kurds alike, with this kind of commerce perhaps offering a glimpse of how Iraq's fractured communities could again live together peacefully.
