Could two major Allied powers still defeat Germany?

Could Germany still be defeated if one of the United Kingdom, United States, or Soviet Union were absent from the war?

Any two of the three could still win, though the route would be bloodier and the duration could change.

In this assessment, Germany would still lose if any one of the United Kingdom, United States, or Soviet Union were absent while the other two remained at war. Britain had considerable economic endurance, and each two-power combination represented overwhelming resources. The routes to victory would differ, and the fighting could become longer and much bloodier, but none of the pairings offers Germany a favourable strategic end state. This is a high-level assessment of resources and staying power rather than a detailed reconstruction of campaigns.
