Answer:
It's a common misconception that Germany did not know they lost the war in World War II. In reality, the German military and political leaders were aware of the dire situation they were in by early 1945. They knew that the Allied forces were closing in on Germany from both the east and the west, and that their military resources were dwindling. However, many German leaders, particularly in the Nazi regime, were determined to fight until the bitter end and refused to accept defeat.
There were also some instances of propaganda and misinformation that may have contributed to the perception that Germany did not know they lost the war. For example, the German government and military leaders sometimes portrayed themselves as fighting a valiant last stand against overwhelming odds, rather than acknowledging that the war was lost.
Overall, while there may have been some elements of denial or propaganda, the idea that Germany did not know they lost the war is largely a myth. The German military and political leaders were aware of their situation, but some chose to fight on until they were completely defeated.
