i do not think he is a muslim, but i do think everyone should see the film 2016 which gives a frank history of his background and influences, his father's view of America as an imperialist misuser of power, etc, and it goes far to explain the psychology behind his ideology. he is simply acting within the parameters of how he feels about this country. he was also greatly influenced by communism (his mentor) and college activities so not a wonder that he is promising Vlad that things would go better after the election.....and he does not mind Iran getting a nuclear weapon.
