ABOARD MILITARY AIRCRAFT, OVER THE BERING SEA - The military has sent 130 advisers to northern Iraq to plan for the evacuation of refugees under siege by Islamic militants, according to a senior Defense Department official.
The Marines and special operations forces have been sent to the city of Irbil in Kurdish-controlled northern Iraq to assess the humanitarian crisis in the Sinjar mountains and ways to end it, said the official who spoke on condition of anonymity because officials were not authorized to speak publicly about the mission.
There are about 300 U.S. military advisers currently in Iraq, as well as other troops there to protect the U.S. Embassy in Baghdad.
The plight of the refugees prompted President Obama to order airstrikes against the ISIS militants and humanitarian airdrops there last week. In an interview with USA TODAY Tuesday, Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, said the military's effort there could take months but will be limited. He added that the effect of the airstrikes had blunted the momentum of the military Islamic State group, and shipping heavier arms to Kurdish allies will help solidify the gains.
The survival of the refugees, including members of the Yazidi sect, has been assured for now, Dempsey said. But their fate and rolling back the gains the Islamic State has made, such as seizing the city of Mosul, will require the new Iraqi government to reach out to Sunnis and Kurds.
"The crisis has been abated but not solved," Dempsey said.
Also Tuesday, Sen. Tim Kaine, D-Va., a member of the Senate Armed Services Committee, called on the White House to seek congressional approval for the airstrikes in Iraq. Kaine supports the humanitarian mission but stressed that the administration needs congressional authority to continue the attacks.
"This is especially the case since the president has indicated that our renewed military engagement in Iraq could be a long-term project," Kaine said in a statement. "I have long stressed that Congress must formally approve the initiation of significant military action."
In the interview, Dempsey talked about the military's mission in Iraq, the threat from the Islamic State and what will be needed to confront it.
He described the Pentagon's role as "limited but I think appropriately so." Its unique capabilities in spy and surveillance aircraft, logistics and targeted airstrikes have filled critical gaps that Iraqi and Kurdish forces could not, he said.
"You hear the term mission creep beginning to make its way around the airwaves," Dempsey said. "What we do is mission match."
Airstrikes in the region won't be needed "in perpetuity" to prevent the slaughter of refugees or to defend Irbil, he said. Instead, the mission could take months.
The threat from the Islamic State has occupied Dempsey — and the Pentagon's attention — for more than a year, he said. Its apocalyptic vision poses a threat, for now, to Iraq and Syria. Unchecked, the group could attack Israel and, ultimately, the United States, he said.
They have successfully coopted, or coerced, many of the 20 million disenfranchised Sunni Muslims living in Syria and Iraq.
'This is a group with a long-term vision," Dempsey said. "And the long term vision is completely antithetical to any of our values."
