Army Lt Gen James Terry, the top commander of Operation Inherent Resolve, the US campaign to defeat IS, also said the nascent effort to rebuild Iraq's army will soon get a boost from coalition countries that plan to commit roughly 1,500 military trainers. Much of the Iraq army collapsed or proved ineffective in the face of IS's onslaught last summer.
Terry said his first priority is to develop more fully an international military coalition against IS.
The US intervened directly starting in August with airstrikes that have damaged IS's fighting force, as well as its economic and logistics bases in Syria. But questions remain about the Iraqis' ability to retake the ground they lost and to sustain a military campaign with President Barack Obama ruling out the use of American ground combat forces.

"I'm comfortable with the boots on the ground that we have right now," he said.
Asked whether the conflict in Iraq is at a stalemate, Terry said, "In some places it's stalemated; in some places it's to the advantage of the Iraqis," meaning the Iraqis have the upper hand now in places like Bayji, site of a key oil refinery north of Baghdad.
"While they still have a long way to go, I think they're becoming more capable every day," he said. That comment is all the more notable for the fact that the US invested billions of dollars in developing the Iraqi security forces during more than eight years of war following the American invasion in March 2003 that toppled President Saddam Hussein.
