I actually calculated the nation strength of the US, China and another country a while back.
The numbers are a little off because the formula has changed, but the numbers should be close since it was primarily infra that contributed to NS.
US NS: 55,621,105.25
China NS: 183,077,797.7
Canada NS: 6,089,259
