Why did it take so long for the world to respond to the atrocities of the Holocaust?

Many did not want to believe, for others; they were already war-weary and they paid little attention to yet more suffering.

Explanation:

America was one of the many countries who, in the beginning, didn't do much for the Jews in the Holocaust. They didn't even let the Jews come in because they didn't want to be a part of it.

the best description of postwar writers might be progressive.

following the war, writers showed a tendency to work on artistic or social matters rather than political themes. while postwar literature may not have been the greatest period of english literature, the themes provided excellent critics a high number of novels. such examples include anthony burgess, anthony powell and frank kermode, all of which can be placed under the progressive view.
