Mattis Says U.S. Using 'Annihilation Tactics' Against ISIS

Defense Secretary James Mattis said Sunday that U.S. forces have entered a new, more aggressive phase in the fight against the Islamic State (ISIS), which he termed “annihilation tactics.”

Speaking on CBS’ Face the Nation, Mattis said the U.S. military has shifted its strategy from attrition, whereby enemies are moved around and denied access to vital supplies, to annihilation, where they are surrounded and unable to escape.
