On June 10, 2015, the pro-Palestinian hacker group AnonGhost successfully hacked and defaced the websites for the U.S. Air Force's Profession of Arms Center of Excellence (PACE) and Professional Development Guide. The defaced pages featured the above image and following message: "YOU SUPPORTED ISRAEL TO KILL INNOCENT PALESTINIAN IN GAZA STRIP BOMBINGS HOUSES AND MOSQUES, ARRESTING AND KILLING INNOCENT PEOPLE IN IRAQ AND AFGHANISTAN USING MEDIA PROPAGANDA TO JUSTIFY YOUR LIES AND YOUR CORRUPT ACT... NOW IT'S OUR TIME TO REACT."
