President Barack Obama has visited more than 50 countries in his eight years in office, and this week he’s taking his final overseas trip as president — a tour of Europe.
Obama has so far spent much of his trip reassuring allies in Europe who are anxious about the unexpected election of Donald Trump and “Brexit,” the British vote to leave the European Union, both of which Obama campaigned against.
On Tuesday and Wednesday, the president visited Greece, where he climbed the Acropolis in Athens, toured the Parthenon and met with Prime Minister Alexis Tsipras. Obama was the first U.S. president to visit the capital city in 17 years, and he thanked Athens for the “most precious of gifts:” democracy.
“The basic longing to live with dignity, the fundamental desire to have control of our lives and our future, and to want to be a part of determining the course of our communities and our nations — these yearnings are universal. They burn in every human heart,” the president said in Athens, the birthplace of democracy.
On Thursday, Obama arrived to Berlin, where he met with German Chancellor Angela Merkel. As he bid farewell to Merkel, whom he recently called his “closest international partner these past eight years,” he assured her — and Europeans in general — that progress will ultimately prevail, despite the current political turmoil.
“I think our politics everywhere are going to be going through a bumpy phase,” Obama said. “As long as we stay true to our democratic principles, as long as elections have integrity, as long as we respect freedom of speech, freedom of religion, as long as there are checks and balances in our governments … then I have confidence that over the long term, progress will continue.”
Obama spent the night in Berlin before continuing on to Peru, where he will meet with Chinese President Xi Jinping and Japanese Prime Minister Shinzo Abe at the Asia-Pacific Economic Cooperation summit in Lima this weekend.
