Democratic presidential contender Barack Obama stood before an enormous crowd in Berlin on Thursday and summoned Europeans and Americans to work together to "defeat terror and dry up the well of extremism that supports it."
Obama spoke from a park not far from where the Berlin Wall once divided the city. In his prepared text, he told Berliners that "the walls between old allies on either side of the Atlantic cannot stand." He spoke of tearing down walls between countries, between races, between religions.
Obama's stop in Germany is part of an international tour designed to burnish his foreign policy credentials as a presidential candidate. He's already been to the Middle East, Iraq and Afghanistan.
