But how might analysts who have been operating out of their "ivory towers" be able to help the U.N. on the front lines, so to speak? It appeared that many of the IPA-U.N. Committee members at the December 13 meeting had already had hands-on experience in some tough situations. One, for instance, had worked with war-traumatized Angolans. Another, from Mexico City, had worked with victims of earthquakes and hurricanes. A third, from Israel, had tried to improve childrearing in Zaire, while another had worked with the families of individuals who had vanished in Argentina. Yet a fifth said he had been working in Croatia, dealing with victims of torture and land mines.
