Just as it depended on what the definition of "is" is, now it depends on what the definition of "war" is and even what the definition of "Iraq" is. The attacks against ISIS are not "war" but instead "explosive kinetic action of an air origin." And they are occurring in the "Kurdish regions of the Middle East" which include not just pieces of Iraq, but also pieces of Syria. As a result, this is not a return to war in Iraq, but "explosive kinetic action of an air origin in the Kurdish regions of the Middle East." That's totally different! (Snark)
