Rich Lowry devotes his latest National Review Online column to a review of recent history in Iraq.

There was a time not so long ago when President Barack Obama boasted of how he had “ended” the Iraq War. It was, in his telling, a sign of his stalwart fidelity to his word.

A video produced by his 2012 presidential campaign was titled “Ending the War in Iraq: A Promise Kept.” In December 2011 his website said: “This month, President Obama is making good on his promise to bring the last American troops home from Iraq in time for the holidays.” The president portrayed the complete withdrawal of U.S. troops as testimony to his exemplary political character. “You know I say what I mean and I mean what I say,” he told crowds during his reelection campaign. “I said I’d end the war in Iraq. I ended it.”

That’s as definitive a statement of responsibility as you get. But now that the president has “restarted” the war in Iraq — with limited air strikes against the terrorist group ISIS, which has thrived in the vacuum created, in part, by our total exit — he is not in such a buoyantly boastful mood.

At a press availability over the weekend about his new bombing campaign, the president kvetched about all those people who keep insisting that he ended the Iraq War: “What I just find interesting is the degree to which this issue keeps on coming up, as if this was my decision.”

It is true that the Bush administration had agreed to end our troop presence, and if we were going to stay, Obama had to negotiate a new status-of-forces agreement with the Iraqis. Why it didn’t happen is a complicated question, and Iraqi resistance is part of the answer. But Obama was perfectly content with the outcome. …

… Iraq is perhaps the purest expression of the Obama doctrine. We removed ourselves entirely from the country on the assumption that we could diminish our influence without baleful consequence and that there were effective substitutes for military power. Now that the most powerful terrorist group of modern times controls large parts of Iraq and neighboring Syria, we are back at war, although without the requisite seriousness or comprehensive strategy.

What is happening in Iraq is exactly what we fought to prevent with the surge in 2007 and 2008. It is heartbreaking commentary on President Obama’s recklessness that we are now in an arguably worse position, with fewer options to reverse it. He never ended the Iraq War, as he so proudly said. He only abandoned it.
