Should countries such as United States, South Africa and Palestine have opened their borders to all the survivors of concentration camps? Why?

Explanation:

In 1945, when Allied troops entered the concentration camps, they discovered piles of corpses, bones, and human ashes—testimony to Nazi mass murder. Soldiers also found thousands of Jewish and non-Jewish survivors suffering from starvation and disease. For survivors, the prospect of rebuilding their lives was daunting.

After liberation, many Jewish survivors feared to return to their former homes because of the antisemitism (hatred of Jews) that persisted in parts of Europe and the trauma they had suffered. Some who returned home feared for their lives. In postwar Poland, for example, there were a number of pogroms (violent anti-Jewish riots). The largest of these occurred in the town of Kielce in 1946 when Polish rioters killed at least 42 Jews and beat many others.
