The most important fact revealed by ISIS’s victory is that the “Iraqi Army” no longer exists. This is a different observation from that of Secretary of Defense Carter, who avers that they lost the will to fight. Some people did lose the will to fight in Ramadi. But, we should ask a more fundamental question. Ramadi was under siege for months. How is it that few if any reinforcements were sent to defend a city deemed critical to the defense of Baghdad itself? Public sources reported some fourteen divisions in the Iraqi Army in 2014. Between three and five were destroyed in Mosul, leaving nine. At most one was defending Ramadi. Where were the rest? Indeed, where are they now? How is it that Shiite militias must be called upon to liberate Ramadi? If the Iraqi Army has evaporated, or perhaps more accurately deteriorated into a collection of local militias and palace guards, then the U.S.“re-training” mission in Iraq is vastly more difficult than we have been led to believe. Having claimed to build an Iraqi Army, which seems not to exist, and which one doubts ever really existed, the U.S. military is now trying to build another one, from the ground up. Why will things turn out better this time?

ISIS’s victory in Ramadi also reveals that it is quite capable, not merely tactically, but at the “operational level.” Put another way, it is good not merely at fights, which require committed fanatics who are good with a gun, but at campaigns, which require canny commanders, logistical support, coordinated mutually supporting battles, movement, and intelligence. In Ramadi, despite U.S. command of the air, ISIS was able to sustain its forces for many months. They were able to manufacture very large truck bombs, requiring tons of explosives, to support their final offensive. They attacked under the cover of a sandstorm, which helped neutralize U.S. air power.
