Pentagon: U.S. strikes have slowed Iraq militants but not weakened them

A series of U.S. airstrikes since last week has slowed the operational tempo of Islamic State of Iraq and Syria militants, the militant group that has seized large parts of northern Iraq, but is unlikely to substantially weaken the group, the Pentagon said on Monday.

“We assess that U.S. airstrikes in northern Iraq have slowed ISIL’s operational tempo and temporarily disrupted their advances toward the province of Erbil,” which includes the capital of Iraq’s semiautonomous Kurdish region, said Army Lieutenant General William Mayville Jr., a senior Pentagon official.

“However, these strikes are unlikely to affect ISIL’s overall capabilities or its operations in other areas of Iraq and Syria,” Mayville told reporters at the Pentagon.

The Obama administration late last week said it would conduct strikes to protect U.S. personnel in Erbil from the militant group, which has gained strength during the war in neighboring Syria, and to ensure that northern Iraq’s minority Yazidis were not subject to systematic violence at the hands of the fundamentalist Sunni Muslim militants.

The 15 airstrikes carried out so far are the first direct U.S. military action in Iraq since the Obama administration completed its withdrawal of U.S. troops at the end of 2011, hoping to mark an end to the long, bloody U.S. military involvement in the country.

Mayville said ISIS, which swept into northern Iraq in a stunning advance in June, remained potent.

The group “remains focused on securing and gaining additional territory throughout Iraq and will sustain its attacks against Iraqi and Kurdish security forces and their positions, as well as target Yazidis, Christians, and other minorities,” he said.
