Not Daesh. Not ISIL. Not IS.
The Pentagon has officially declared the name of the terror group the United States and its allies have been fighting for years is, in fact, ISIS.
“We have officially switched to ISIS,” Capt. Jeff Davis, a Pentagon spokesman, said in a briefing with reporters Friday. “They all mean the same thing.” Davis said ISIS already had been used unofficially in the past inside the Pentagon because it was the “easiest to understand.”
