No it wasn't. Any nations advancement costs lives, lots of them.
Care to explain Sweden? Were did we lost a lots of life during the last 200 years? And we had a lot of advancement during this time.

Chinas culture was older and more sophisticated. And Stalin murders were a bit over the top. He killed people for kicks it seems. I can excuse his creating a famines becuase well we all make mistakes, and when your Czar a mistake costs lives.
As the Chinese culture is the oldest now existing culture on earth I'm assume that we all should skip our culture to use the much more superior Chinese culture?

That depends on whether the Chinese gave me an opportunity for advancement and a better life. It wold be obvious that all resisting the Chinese equals death, and since I want to live. I'd tow the line.
So as long as you (not all of your people) will (possibly) get opportunity for advancement and a better life, by an invasion force, you're willing to surrender everything else?
