From Nov. 9: Joshua Landis interviewed by RT (Russian English-language TV) (h/t). One point that goes beyond the immediately topical is his argument that there are no state apparatuses in the M.E. separate from the particular regimes that are in control; hence, regime change always means chaos. I might have some further comment on it later.
ETA: See also, somewhat relatedly, this widely linked piece in The Nation from last month, describing interviews with ISIS fighters being held as prisoners in Iraq. Interesting on the issue(s) of motivation.
