In Warsaw, Trump delivered a starkly nationalist speech lauding the right-wing Polish government’s defense of “civilization” from foes like refugees and European Union bureaucrats. At the G-20 summit in Germany, Trump stuck to his dissent from a global climate change consensus, befriended Russian President Vladimir Putin and weighed potential new steel tariffs that a top European Union official angrily branded “protectionist.”

In each instance, the influence of nationalist White House advisers, like Steve Bannon and Stephen Miller — along with Trump’s own raw instincts — were on clear display. And all represent setbacks for the likes of National Security Adviser H.R. McMaster and chief economic adviser Gary Cohn, who are trying to steer Trump’s policies in a more conventional direction.

“Overall the trip embraced nationalism much more than internationalism,” said Richard Haass, president of the Council on Foreign Relations.
