"..., while Hitler may have not used this exact phrase, making Germany great again was a dominant theme in Nazi propaganda. The mood in 1930s Germany was dark; the country had been hit especially hard by a global economic recession, and was still stinging from a humiliating defeat during the first World War fifteen years before. Adolf Hitler's main message was one of redemption for the country."
and of course, "Seig Heil" means "Hail Victory" similar to "We're gonna win and win"
