What explains the change? Above all, it’s the legend of the surge. The legend goes something like this: By sending more troops to Iraq in 2007, George W. Bush finally won the Iraq War. Then Barack Obama, by withdrawing U.S. troops, lost it. Because of Obama’s troop withdrawal, and his general refusal to exercise American power, Iraq collapsed, ISIS rose, and the Middle East fell apart. “We had it won, thanks to the surge,” Senator John McCain declared last September. “The problems we face in Iraq today,” Louisiana Governor Bobby Jindal argued in May, “I don’t think were because of President Bush’s strength, but rather have come about because of President Obama’s weakness.”
