Steve Bannon has been appointed the chief strategist for Donald Trump and he is seen as an ultra right wing nationalist and some see him as a white-supremacist.
This on top of the fact that in Trump's election campaign he said derogatory things about Muslims, Mexicans, and other minority communities.
On foreign policy, he seems less interventionist than Clinton and would not seek to confront Russia. That said, Trump seems extremely unpredictable and has promised to beef up the military, so virtually anything could happen if he gets elected.
John Bolton seems likely favorite to be Donald Trump's new secretary of state. He has been openly hostile to Iran and the Iranian. However, he is a keen admirer of Putin so only time will tell what this means and what his foreign policy will truly be like.
