We are engaged in a very significant counterterrorism operation with ISIL. We have always been engaged in a very significant counterterrorism operation with ISIL.

"We at war with ISIL... In the same way that we are at war with Al Qaeda and its affiliates around the globe...”
White House press secretary Josh Earnest

"At this moment, for example, in 1984 (if it was 1984), Oceania was at war with Eurasia and in alliance with Eastasia..."  George Orwell 1984

"First, we will conduct a systematic campaign of airstrikes against these terrorists. Working with the Iraqi government, we will expand our efforts beyond protecting our own people and humanitarian missions so that we’re hitting ISIL targets as Iraqi forces go on offense. Moreover, I have made it clear that we will hunt down terrorists who threaten our country, wherever they are. That means I will not hesitate to take action against ISIL in Syria as well as Iraq."  - President Barack Obama - 9/10/14

So now we are at war with the ISIL Sunni terrorist rebels in Syria and Iraq in support of the Post-Maliki Iraq government (after we helped pressure him out),  which aligns us with the Shia Iranian regime, Syria's Assad regime, and Russia.

"In no public or private utterance was it ever admitted that the three powers had at any time been grouped along different lines. Actually, as Winston well knew, it was only four years since Oceania had been at war with Eastasia and in alliance with Eurasia. But that was merely a piece of furtive knowledge, which he happened to possess because his memory was not satisfactorily under control. Officially the change of partners had never happened..."  - George Orwell 1984

"... after careful deliberation, I have decided that the United States should take military action against Syrian regime targets. This would not be an open-ended intervention. We would not put boots on the ground. Instead, our action would be designed to be limited in duration and scope. But I'm confident we can hold the Assad regime accountable for their use of chemical weapons, deter this kind of behavior, and degrade their capacity to carry it out."  - President Barack Obama - 9/10/2013

And one year ago, we were aligned with Sunni Syrian rebel in opposition to the Shia Assad regime and their allies Iran and Russia.
