WASHINGTON (AP) — For all its horror, the beheading of an American journalist in Syria appears unlikely to change lawmakers’ minds about military intervention against Islamic State extremists. It’s equally unclear whether the Obama administration will be asking them to back a new U.S. approach.

President Barack Obama said the United States wouldn’t scale back its military posture in Iraq in response to James Foley’s killing. But he offered no specifics Wednesday about what new steps he might take to protect additional captives and other Americans, and ward off what he described as the al-Qaida offshoot’s genocidal ambitions.
