FWIW, Switzerland has a higher GDP per capita at $82k as compared to $62k for the U.S. Swiss per capita defense expenditures are closer to ~1/4 (28%) of those of the U.S. as compared to ~1/5 (21%) when judging by GDP percentage. (Conversely, France and U.K. have GDPs of about $42k, so they compare much worse by that metric.)

But more importantly, Switzerland isn't a NATO member.
