Who would you prefer to be in charge of the WMDs — ISIS or Saddam?
(It was never suggested that Saddam had his agents inside the US. Can you say the same about ISIS?)
The right scenario would hae been for Obama to support Maliki. Obama didn't talk to Malike ONCE since 2009. He watched Iraq crumble with gratification. He didn't want to move Iraq forward because he didn't want Bush to take the credit for bettering Iraq.
