Bush aircraft carrier in the Mediterranean Sea, in preparation for sorties on Islamic State group positions in Iraq and Syria. IS, the ultra-extremist group responsible for some of the worst atrocities perpetrated against civilians in recent history, is on the verge of collapse. The group that brutalized residents living under its command for more than three years is fighting to hang on to remaining pockets of territory in Iraq and Syria, besieged by local forces from all sides.
