I really don't see this. Yes, I think his instincts are probably socially liberal, he is a New Yorker after all, but I don't see him as a "foreign policy dove". He's an egotistical narcissist, on a level I've rarely observed on the national scene ... perhaps Kanye West? When ISIS, or Assad, or Putin, or Iranian ayatollahs or Kim Jong-un or whoever, challenges the US, challenges President Trump, he's likely to take it personally. With the US military at his disposal, I don't see him stepping back from a military response. As I've remarked previously, every US President has been drawn into foreign interventions, even, like Obama, against their own inclinations. I would trust Trump less than almost any other candidate to react in a thoughtful measured way.
