Over the eight years of his presidency, Barack Obama has dined with Queen Elizabeth II in Buckingham Palace, raised a glass of Guinness beer in Ireland and toured the Acropolis in Athens.
Obama is making his sixth and final visit to Germany as a sitting president this week, but he says he'd like to come back as a former president to attend Octoberfest. "I'll have more fun," he says.
His trips to Europe have included somber occasions, such as his participation in a wreath-laying ceremony at the Tomb of the Unknown Soldier in Moscow and meeting with Holocaust survivors at the Warsaw Ghetto Memorial in Poland.
Obama has sought to reaffirm during his presidency that the U.S. commitment to Europe is enduring.
The spelling of 'soldier' has been corrected in the 3rd paragraph.
