Didn't know this. During the Civil War, General Grant expelled Jews from Tenn. Lincoln countermanded Order when he learned of it, “To condemn a class is, to say the least, to wrong the good with the bad,” the president declared. “I do not like to hear a class or nationality condemned on account of a few sinners.”
Grant acted to redeem himself for that Order, the rest of his life.
I am certain that if President Lincoln did not countermand that edict, the North would have lost the war and America would have been lost as well. There was a similar result in 1940’s Great Britain when politicians kept the Jewish refugees from escaping the Nazi’s, and the “empire where the sun never set” dwindled to merely Northern Ireland.
