The Jews of Sighet are optimistic because of the news they hear on the radio in late 1942 and 1943. What is the news and why are they so optimistic?

The News on the radio was the daily bombing of Germany and Stalin, the preparation of the second Front. this made the Jews of Sighet believe that there were better days yet to come. They believed Hitler would not be able to harm them. I found this answer in the translation book by Marion Wiesel, page 8.
