A German magazine speculates earlier this month on what Obama might talk about. He'll speak at the Victory Tower.
Spiegel: A July 24 date has been set by the campaign for a Berlin visit and more details are gradually emerging. During his visit to the German capital, Obama plans to hold a keynote address on trans-Atlantic relations.
"During this campaign, Senator Obama has been criticized for his lack of interest in Europe," an Obama campaign adviser with knowledge of the planning for the trip told SPIEGEL ONLINE. "This trip is partly a response to this, and I am sure he wants to address the issue of trans-Atlantic relations."
The possibility has not been ruled out that the speech could instead be given in Paris or London -- the other stops on Obama's short Europe trip. But Obama's team likes the location of Berlin and the Brandenburg Gate. "The setting would be great," the advisor said. "The memory of John F. Kennedy's famous Berlin speech is still alive. Berlin is a bridge between East and West, and the German-American relationship is very strong," said the advisor.
