But Obama never used the word "war" to describe his decision to launch airstrikes against ISIS and provide military assistance to regional forces fighting the extremist group. When he employed the w-word, it was to clarify what this is not. It's not "another ground war in Iraq." It's not Afghanistan. It's a "counterterrorism campaign" to "take out ISIL wherever they exist." Obama didn't say how long the campaign would take, or how we'll know when its mission is accomplished.
