The above interview with Dr. Vijay Prashad draws our attention to the parallel conflicts of Libya and Syria, as well as the way the two wars directly intersected in 2011-2012 (weapons shipments from Libya to Syria, now fully documented via USG declassified reports).
One of the more interesting points comes when Dr. Prashad speaks about ISIS presence in Sirte, Libya. He claims that just as many former Ba’ath officers in Iraq, after having been sidelined by U.S. intervention, joined ISIS, so are former Gaddafi loyalists joining Libyan ISIS in Sirte.
While it’s unclear whether or not there is actual evidence for this it is a worrisome and fascinating theory. Prashad is the only analyst I’ve heard propose this.
I would highly recommend his book Arab Spring, Libyan Winter. The above interview is a must-see.
