Iraq was an artificial construct by the British, in 1918.
Like Yugoslavia, it hung together only while there was a ruthless strongman in charge.
It’s demise was inevitable without a strongman.
Obama supported this group when it was in Syria, part of the so-called rebels fighting Assad.
I’ve wondered if Obama would like to see them become Iraq’s ‘strongman’ again. Push Hillary’s famous ‘reset’ button and go back to Sunni Hussein dictating for the entire area. (Most of Indonesia is Sunni, btw. I wonder if we should factor that into our consideration of Obama’s thoughts? Especially in light of his obeisance to the King of Mecca who also is Sunni.)
