It would be relevant to have an estimate of how many lives would have been saved if we’d left some forces in Iraq. I don’t know but it seems likely that the Sunni wouldn’t have been marginalized and ISIS might not have assumed its current size.
As Rudy Giuliani said last week on Varney and Company, Obama and Hillary should be considered ‘founding members of ISIS’.
And as you know Giuliani knows a thing or two about terrorism.
