President Barack Obama thanked US government counter-terrorism employees, crediting them with "making real progress" in disrupting al-Qaeda and other extremist groups. “The record of your service is written in the attacks that never occur because you thwarted them,” Obama told his audience at the National Counter-terrorism Centre outside Washington. But enemies are still around “still plotting” he said. Obama's visit was designed to give a lift to analysts who work at the centre, a multi-agency body organised after 9/11. Obama said he draws on the centre's output every day in formulating his national security decisions.
