Which u. s. organization was designed to aid eastern european jews?

The War Refugee Board

Explanation:

The International Organization of Refugees (OIR) was a non-governmental organization founded on April 20, 1946 to solve the problem of refugees (mostly European Jews) created by World War II. A preparatory commission began operations fourteen months earlier. In 1948, the treaty establishing the RIO formally entered into force and the RIO became a specialized agency of the United Nations. The OIR took over most of the functions of the former United Nations Relief and Rehabilitation Administration. In 1952, OIR operations were discontinued and replaced by the United Nations High Commissioner for Refugees (UNHCR).
