What did America do and how did it act to the holocaust?
The answer is not pleasant.
The first thing that should be said is: anti-Semites were wide-spread in the 1940's. one influential anti-Semite was Breckinridge Long who put in more immigration laws limiting the amount of immigrants allowed in. Although i do not have the exact dates of years but because of the barriers put in place by Long immigration was cut in half, then nearly stopped at one point during WW2.
