You're forgetting the unique differences in geography and demographics of the USA area compared to what the germans, french and russians had to "work" with.
annual average temperature about 23 °F vs Average temperature: 55.7°F
Also, completely different time frame and technology standard.
Sibera might have given russia some value, but not remotely on the same scale as north america gave to the USA.
Could there be other things at play, like absolute autocracy dominating the Russian state even today? The Germans had plenty of space and resources had they not lost it trying to dominate their neighbors.
