American newspapers during the war had very little information about concentration camps, and what the Nazis were accomplishing. The verified facts, and stories were not let out until after the war. Journalists had no idea what was going on at the time because the Nazi’s had their tactics of keeping everything a secret. The situation was similar in the European countries, the facts and gruesome stories were released post World War II.
The photographs below are of American newspapers that were published during the war, from the headlines down to the stories nothing explains anything about the Jewish collapse. Hitler had incredible ways of keeping outrageous events out of the press and media of other countries. The first photo is of a newspaper ran in Fairbanks Alaska a few days after Hitler invaded Poland on September 1, 1939. The second photo is from Joplin Missouri, this newspaper is from 1945 and it is focused on when the Soviet and American troops met up at a river. This day they took out an important communications hub for Germany.
