His 26-hour whirlwind visit to the German capital caps three days of international summitry for the president and marks his return to a place where he once summoned a throng of 200,000 to share his ambitious vision for American leadership.
Obama will make the case for his nuclear plan during a speech at Berlin's iconic Brandenburg Gate. His address comes nearly 50 years after John F. Kennedy's famous Cold War speech in this once-divided city, and five years after Obama spoke in the city during his 2008 run for president.
The president has previously called for reductions to the stockpiles and is not expected to outline a timeline for this renewed push. But by addressing the issue in a major foreign policy speech, Obama is signaling a desire to rekindle an issue that was a centerpiece of his early first-term national security agenda.
Five years later, Obama comes to deliver a highly anticipated speech to a country that's a bit more sober about his aspirations and the extent of his successes, yet still eager to receive his attention at a time that many here feel that Europe, and Germany in particular, are no longer U.S. priorities. A Pew Research Center poll of Germans found that while their views of the U.S. have slipped since Obama's first year in office, he has managed to retain his popularity, with 88 percent of those surveyed approving of his foreign policies.
Obama also has an arc of history to fulfill.
Fifty years ago next week, President Kennedy addressed a crowd of 450,000 in that then-divided city to repudiate communism and famously declare "Ich bin ein Berliner," German for "I am a Berliner." Since then, presidents from Ronald Reagan to Bill Clinton have used Berlin speeches to articulate broad themes about freedom and international alliances.
