That’s not a safe assumption. The US was awfully busy fighting the Japanese. Had they stayed out of Europe, Hitler would certainly have defeated Britain (leaving Africa unprotected) and likely had the resources spare to defeat the USSR too. From there Hitler could support the Japanese against the US and would have massive resources to do so. Hitler’s plan really was world domination. He had plans for a rocket-powered trans-Atlantic plane to bomb New York. Not to mention that the Nazis had the V2 and even a jet fighter by the end of the war (but too few resources to build/deploy them). With more resources the Nazis may well have developed their nuclear bomb.
