Obama Admits: US Underestimated ISIL

Speaking to CBS News, Obama said that former Al-Qaeda fighters driven from Iraq by US and local forces had been able to gather in Syria to form the newly dangerous ISIL.
  
"I think our head of the intelligence community, Jim Clapper, has acknowledged that they underestimated what had been taking place in Syria," Obama said, referring to his director of national intelligence.
  
Asked whether Washington had also overestimated the ability or will of Iraq's US-trained military to fight the terrorists on its own, Obama said: "That's true. That's absolutely true."
