If we want to understand why President Obama has broken yet another major campaign promise and ordered America's return to Iraq, the key question to ask is: Why now?
After all, the Islamic State in Syria/al-Sham (ISIS) has been scoring dramatic military gains for months, and yet in spite of that the President stubbornly resisted calls by Republican hawks to give Baghdad air cover. Nine-hundred special forces were sent in to "train" the Iraqis and coordinate strategy, but Obama insisted they would not go into combat and air strikes were considered out of the question. No matter how loudly John McCain yelped, and his Pekinese who goes by the name Lindsey Graham barked, the White House was adamant about not re-engaging.
So what happened?
