""Davon geht die Welt nicht unter"" and ""Ich weiß, es wird einmal ein Wunder gescheh'n"" were two of the biggest hits of the National Socialist period, and because of their political subtexts were much approved of and promoted by the authorities.After 1942, as the military situation became more and more unfavourable to Germany, they became a staple element of the prevalent informal propaganda geared to "seeing it through".
