They believe that if we in the United States live up to our pledges. and if England and France will stand with us and with West Germany. Khrushchev will have to back down. Yesterday I visited the refugee reception center at Marienfelde. This was a scene of heartbreak. of sorrow. and of sadness the like of which I have never before seen. and I think that in my lifetime I have seen sorrow and sadness. and yet there was also hope. Here were thousands of people who could have been your neighbors. people of all ages. old and young. mothers and babies. penniless. homeless. separated from their families.
