Conley said Obama’s trip, planned when it seemed certain Hillary Clinton would win, had been designed to reassure the world that the U.S. had regained its footing after an toxic campaign that unnerved foreign capitals. “Now the president has the unenviable task of telling his counterparts and explaining what Europeans are now coining ‘the Trump effect,'” Conley said…

Ben Rhodes, Obama’s deputy national security adviser, said the president fully expects Trump’s election to be a dominant theme of the trip, but would emphasize his plans to keep carrying out his approach until Trump takes over. He said Obama would argue that basic U.S. principles like honoring treaty commitments have historically survived even the most dramatic changes of administrations.

“He’ll want to use these conversations with leaders to express that view that given all the important issues that we face, no matter what our preferred choice may have been in the election, right now we as Americans have a stake in seeing this next administration succeed,” Rhodes said.
