Then recall what we did afterward-- the Marshall Plan, massive help in rebuilding their countries both materially and socially.
Compare and contrast that to what the North did to the South-- looting carpetbaggers, ruinous taxes and disenfranchisement of all but the lowest level Confederate veterans. Lincoln would have done a much better job of reconstruction than the looters who played the two well-meaning but incompetent administrations which followed him like a fiddle. In some ways the damage done to the south in the 12 years after the war exceeded the damage done during the four years of war and we are still living with the part of that sorry legacy which elevated grievances, revenge and equal results (as defined by our modern carpetbaggers) over forgiveness, individual effort and equal opportunity.
And I though we were talking about the involvement of Jewish soldiers in the Confederate Army.
The south received far better treatment post war than the losers of any other insurrection in history. Take a look at losing side of the French Revolution, the Russian Revolution, and rebellions in Britain, Italy, Spain, and China for example.
