Video showing the beheading of American photojournalist James Foley by an Islamic State militant has been confirmed by U.S. officials. President Obama called the terrorist ideology a “cancer” and vowed to bring those responsible to justice. In the video Foley — missing since 2012 — pleads against U.S. intervention in Iraq. After the beheading, the executioner warns that Obama’s “next decision” will decide the fate of another kidnapped U.S. journalist. Targeting Americans may not be the group’s top priority now, “but there can be little doubt this is among its ambitions,” warns former CIA deputy director and OZY contributor John McLaughlin.
