ISIS Threat - Didn't US Spend $Billions on Training the Iraqi Army?

In a televised speech marking the 94th anniversary of the founding of Iraq's army, Iraqi Defense Minister Khaled al-Obeidi acknowledged that a number of weaknesses, including poor leadership and training!! led to the country's forces' defeat by IS jihadists in parts of Iraq.
"We are still in the early stages; some of them are known to you, and some remain in secret," the defense minister said Tuesday. "Weak leaders and incompetent members assuming the chain of command, a lack of disciple, weak training, poor performance and the disintegration of public trust in the security forces… were the reasons for the setback," he added.
