Within weeks of the Great War’s outbreak, American Jews rushed to send relief for Jews caught in the crossfire of crumbling empires. To aid Jewish war sufferers, American Jews founded the Joint Distribution Committee. To move aid in wartime, American Jews worked with the US government, the largest neutral power. Cash aid traveled to Jews in war zones through the US diplomatic pouch and family connections. Preexisting Jewish organizations in Europe delivered the monies. The war promoted the growth of new American charitable organizations, and these organizations took their American visions abroad to help others, with the support of the US government, which had no government programs like USAID in place at the time. American Jews joined America’s expanding state at the critical juncture of the war, wandering into the center of American foreign policy and less official humanitarian relief initiatives to carry out basic relief to Jews abroad. They became more “American,” while relying on the Jewish diasporic network and immigrant practices.
