NYTimes also mentioned that any sustained military campaign does not appear imminent. It is also likely to require an even more significant commitment from other nations and fighting forces in the region.
The US administration and military officials have laid out a battle plan that would not accelerate in earnest until disparate groups of Iraqi forces, Kurds and Syrian rebels stepped up to provide the fighting forces on the ground.
Officials told press that equipping, training and coordinating that effort is a lengthy process.
The US officials have already made it clear they do not want the airstrikes to get ahead of the ground action against ISIS. This is going to take some time to be implemented. "This isn't going to be ‘shock and awe' with hundreds of airstrikes," one official said. "We don't want this to look like an American war."
Iraqi officials have been trying to make their next step clear. The United States has already carried out more than 150 airstrikes since Obama announced the campaign to destroy ISIS earlier this month.
"The Iraqis have asked for assistance in the border regions, and that's something we're looking at," said a State Department official.
