Friday, November 22nd, marks 50 years since the assassination of President John F. Kennedy in Dallas. At the time, the Cold War between the United States and the Soviet Union was at its height, and there was no greater flashpoint than the divided city of Berlin. President Kennedy spoke there just months before his assassination. VOA’s Jeff Swicord went back to see how the president's famous call to freedom still echoes across a now unified Berlin. The piece is narrated by VOA correspondent Jim Malone.
