Baghdad: Expelled from their main stronghold in northern Iraq, Islamic State militants are now trapped in a military vise that will squeeze them on both sides of the Syria-Iraq border, US Defense Secretary Jim Mattis said.
Mattis arrived in the Iraqi capital on an unannounced visit Tuesday just hours after President Donald Trump outlined a fresh approach to the stalemated war in Afghanistan.
Trump also has vowed to take a more aggressive, effective approach against ISIS in Iraq and Syria, but he has yet to unveil a strategy for that conflict that differs greatly from his predecessor's.
In Baghdad, Mattis was meeting with senior Iraqi government leaders and with US commanders. He also planned to meet in Irbil with Massoud Barzani, leader of the semi-autonomous Kurdish region that has helped fight ISIS.
Mattis told reporters before departing from neighboring Jordan that the so-called Middle Euphrates River Valley roughly from the western Iraqi city of al-Qaim to the eastern Syrian city of Der el-Zour -will be liberated in time, as ISIS gets hit from both ends of the valley that bisects Iraq and Syria.
"You see, ISIS is now caught in-between converging forces," he said, using an alternative acronym for the militant group that burst into western and northern Iraq in 2014 from Syria and held sway for more than two years. "So ISIS's days are certainly numbered, but it's not over yet and it's not going to be over any time soon." Mattis referred to this area as "ISIS's last stand."
Unlike the war in Afghanistan, Iraq offers a more positive narrative for the White House, at least for now. Having enabled Iraqi government forces to reclaim the Islamic State's prized possession of Mosul in July, the US military effort is showing tangible progress and the Pentagon can credibly assert that momentum is on Iraq's side.
Brett McGurk, the administration's special envoy to the counter-ISIS coalition, credits the Trump administration for having accelerated gains against the militants. He said Monday that about one-third of all territory regained in Iraq and Syria since 2014 has been retaken in the last six or seven months.
"I think that's quite significant and partially due to the fact we're moving faster, more effectively," as a result of Trump's delegation of battlefield authorities to commanders in the field, McGurk said. He said this "has really made a difference on the ground. I have seen that with my own eyes."
It seems likely that in coming months Trump may be in position to declare a victory of sorts in Iraq as ISIS fighters are marginalized and they lose their claim to be running a "caliphate" inside Iraq's borders.
Syria, on the other hand, is a murkier problem, even as ISIS loses ground there against US-supported local fighters and Russian-backed Syrian government forces.
The US role in Iraq parallels Afghanistan in some ways, starting with the basic tenet of enabling local government forces to fight rather than having US troops do the fighting for them. That is unlikely to change in either country. Also, although the Taliban is the main opposition force in Afghanistan, an Islamic State affiliate has emerged there, too.
In both countries, US airpower is playing an important role in support of local forces, and in both countries the Pentagon is trying to facilitate the development of potent local air forces.
In Iraq, the political outlook is clouded by the same sectarian and ethnic division between Sunni, Shiite and Kurdish factions that have repeatedly undercut, and in some cases reversed, security gains following the toppling of Saddam Hussein's regime in 2003.
An immediate worry is a Kurdish independence referendum to be held Sept. 25, which, if successful, could upset a delicate political balance in Iraq and enflame tensions with Turkey, whose own Kurdish population has fought an insurgency against the central government for decades. McGurk reiterated US opposition to holding the Iraqi Kurdish referendum.
"We believe these issues should be resolved through dialogue under the constitutional framework, and that a referendum at this time would be really potentially catastrophic to the counter-ISIS campaign," McGurk told reporters in a joint appearance with Mattis before they flew to Iraq.
With the Iraqi military's campaign to retake the northern city of Tal Afar now under way, Mattis has refused to predict victory. He says generals and senior officials should "just go silent" when troops are entering battle.
"I'd prefer just to let the reality come home. There's nothing to be gained by forecasting something that's fundamentally unpredictable," he told reporters traveling with him over the weekend.
