President nothing demonstrates more poignantly the mixed signals we are getting from the Soviet Union than a very sad event. On Tuesday a funeral was held here in Washington for a woman named Ina Meiman. Mrs. Meiman. who with her husband Nuam. was finally allowed to come to the United States 1 month ago to receive special treatment for cancer. Her husband. however. was denied an exit visa. The visa came too late to do Ina Meiman any good. And she died here without her husband by her side. And nothing demonstrates more graphically the contradictions than the spectacle of thugs beating up Jews demonstrating on behalf of imprisoned dissident Josef Begun.
