Would people in Germany today be better off if the Nazis won?
Would people in Japan be better off if Imperial Japan had won?
In both cases I think it very unlikely.
It is an easy mental shorthand to think of what a country “wants” by the actions of their government, or what is good for the country as being what the will of the current government is. But it is important to keep the people seperate from the country, of course the government has a large part to play in the lives of the people, but the desires of the elite in control are not the same thing as what makes life for the average citizen good, and certainly not the will of all of the people in a country.
国家是国家人还是人
What people anywhere need to flourish is safety and freedom, there are cultural differences, group differences, differences of all kinds, but in the end we are so much more the same than we are different.
