The Russians are paper tying and the more we learn about the Soviet Union the more we learn how weak Russia was
There's too much corruption and internal problems relate to the Russian system that means it's not a true power .
The nation of Italy is richer then Russia
As for China they got a lot of issues internally to deal with as well as the potential of his population going from 1.4 billion
To potentially under 500 million within this century
Also China need the US navy to protect international trade it was a mistake to antagonize the United States
They should have waited another 50 years
