It has become “commonplace” to argue that Syria’s five-year civil war and the breakdown of post US-invasion Iraq has split Middle Eastern states into their pre-Sykes-Picot agreement “ethno-sectarian fragments,” writes David Gardner. However, he says, “a fuller picture of what is happening in the Middle East today might look at what came before Sykes-Picot as well as what came after.” [Financial Times]

The visit must mark a renewed commitment to this pledge, backed up by deeds: taking US nuclear weapons off “hair-trigger alert,” limiting them to deterrence only, and scrapping plans to build a new wave of nuclear weapons. [Washington Post]
