I am convinced that Trump doesn't have a foreign policy. In fact, I don't think he has a set policy on anything. His "policy" changes daily, maybe hourly. Depends on who has his ear at any given moment.
Bolton knows his stuff. Had Trump actually listened to him, we wouldn't have the chaos we have now.
I tend to agree. Trump doesn't seem to have a foreign policy, nor set policies, and yes indeed his policies seem to change with which ever way the wind is blowing. I believe that he is largely influenced by his Princess and her frog. I think most of us called it right; we were afraid he wouldn't take the advice given to him from the experts. If he doesn't like the advice given, he dismisses them or uses them as scapegoats.
