“Scatterbrained” is actually the least of it. “Potentially very dangerous” is the real deal. I’m quoting the end of Juan Cole’s analysis of the apparent endgame in Syria.
The Russo-Iranian Middle East would have been a challenge to President Obama’s vision of the area, but it isn’t clear that it would bother Trump. Trump has argued in the past for turning Syria over to the Russians.
The big contradiction here is that Trump has nominated extreme anti-Iran conspiracy theorists to his administration. Gen. James “Mad Dog” Mattis, appointed to Sec. of Defense, has suggested that Iran created Daesh (ISIS, ISIL), which is sort of like alleging that the papacy was and continues to be behind the Lutheran church.
Likewise incoming National Security Adviser Mike Flynn is a big anti-Iran figure.
So while Trump himself has indicated an ability to live with a Russo-Iranian Middle East, his cabinet will be made extremely upset by it.
