> What's the difference between France (lost quickly in WWII), Britain (barely evaded invasion), and the US (not invaded, economy grew during the war)?

A lot of it is location, to be honest. Invading the U.S. was nowhere near as easy as invading France, Poland, etc. for Germany (or Japan, for that matter).

I think the closest we got to invasion during the war (outside Pearl Harbor) were some isolated submarines off the coast of Oregon: https://en.wikipedia.org/wiki/Bombardment_of_Fort_Stevens

Several Aleutian Islanda were taken over by the Japanese, as were Wake, Guam, and the Philippines.
