Defense Secretary Ash Carter said Wednesday that leaders at a counter-Islamic State meeting expressed concerns about what happens after the expected defeat of the militant group, and whether countries are ready to help stabilize and rebuild the war-torn cities in Iraq and Syria.
Carter also said that some nations have agreed to step up their contributions to the fight, as battles for the key cities of Mosul in Iraq and Raqqa in Syria loom.
Defense and foreign leaders from more than 30 countries are in Washington for two days of meetings on the next steps to be taken in the fight to defeat the Islamic State group, which still maintains control of large sections of Iraq and Syria.
Speaking to reporters after the first day's session wrapped up at Joint Base Andrews, Carter said a lot of the conversations were about identifying the needs for reconstruction after the battles are over. They worried, he said, that stabilization and reconstruction will lag behind the military operations.
He said the ministers want to make sure "that our planning and execution" of those post-battle needs are aligned with the military effort.
In comments kicking off the meeting, Carter urged a gathering of defense leaders to do more in the fight against Islamic State group in Iraq and Syria, as they huddled to map out the next steps in the campaign.
"We must ensure that our partners on the ground have what they need to win the fight and then hold, rebuild, and govern their territory," he said. "We must not rest."
Defense and foreign ministers are in Washington for two days of meetings as the fights for key cities in Iraq and Syria move forward.
The gathering comes as Iraqi security forces, aided by the coalition, are preparing to encircle and eventually attempt to retake the key northern city of Mosul. The meeting of defense leaders lasted about two hours. They were expected to see a military demonstration after lunch, before adjourning.
This is the fourth time that Carter has convened an anti-Islamic State coalition meeting.
Secretary of State John Kerry was hosting a separate conference at the State Department Wednesday to try to raise at least $2 billion from donor nations to help Iraq as it takes territory from the Islamic State group.
"This is a cause that truly deserves a firm and generous commitment from everybody," Kerry said. The money will go to humanitarian aid for displaced people, demining, immediate help to recently liberated communities and the people returning to them as well as medium-to long-term reconstruction and development assistance. The U.N. estimates that there are currently 10 million Iraqis in need of assistance and that number is likely to exceed 13 million by year's end.
On Thursday, Kerry will host a joint meeting of defense and foreign ministers in the counter-IS coalition. They are expected to talk about the coordination of political and military efforts, including counter-terrorist financing, combating the flow of foreign fighters, and the stabilization of cities and towns that have been freed from Islamic State control.
"We are succeeding on the ground in Iraq and Syria but we have a lot of work to do," said Brett McGurk, the president's special representative to the counter-IS coalition. "This is an enormous challenge that will be with us for years to come."
The gathering comes on the heels of the NATO summit in Warsaw earlier this month, when allies agreed to boost support for the anti-Islamic State mission, including the launch of a training and capacity-building mission for Iraqi armed forces in Iraq,
The U.S. has announced that it will send 560 additional troops to Iraq to transform a newly retaken air base into a staging hub for the long-awaited battle to recapture Mosul from Islamic State militants.
The coalition is also looking to reinforce the fight in Syria, where U.S.-backed forces are in a tough fight for the town of Manbij.
Manbij lies on a key supply line from Turkey to the Islamic State's de facto capital of Raqqa. Ousting the militants from Raqqa is a key goal for the coalition.
