Politico: “European leaders think Trump is mentally unstable … The president’s wild shifts in tone left many NATO allies concluding no hidden strategy lies behind his unpredictability.”
“Nobody knows when Trump is doing international diplomacy and when he is doing election campaigning in Montana. It is difficult to decode what policy the American president is promoting.” — Danish Defense Minister Claus Hjort Frederiksen.
“You know the way he speaks, you cannot take him literally.” — a senior NATO official.
“He speaks a language that doesn’t match with diplomacy. We were used to the Brits, who speak a more frank diplomatic language, but this is another thing.” — a European Union official.
“Sometimes tweets are more important than what is negotiated.” — French President Emmanuel Macron
