"We ask that you, our elected officials, do everything in your power to stop our country from enacting isolationist policies and fencing ourselves off from the world in which we live," they wrote in a letter to all 535 members of Congress signed by more than 200 scholars, Haaretz newspaper reported.
"The 'benefits' of isolationism will pale in comparison to the risks it poses to refugees and immigrants and to the very founding ideals of the United States of America. Those ideals-and the people brought to our country as a direct result of them-have inspired the best in all of us. Join us in protesting policies and orders that threaten these American ideals and use your positions to advance legal protections for refugees and all classes of immigrants," the letter read.
"As scholars of Jewish studies, we devote our lives to studying a people defined, in part, by its experiences of expulsion and refugeehood," the professors wrote.
"Throughout their history, Jews have been expelled or barred from entry from countries on the grounds of their perceived threats to security and unity. While Jews found refuge in the US throughout the 19th and early 20th century, in the 1930s and 1940s, Jewish refugees from Nazi-occupied countries suffered at the hands of our country's then-newly enacted restrictive immigration policies," they said.
