What's the definition of "superpower"? I did not see this word anywhere in the thread.
Between 1960 and 2016 the GDP in the US went up 1900%, China went in the same period up 9076% (76 th place, not 100th). At this speed they will soon jump over the US.
It is funny to see how a mouse (China) can make a giant (USA) so nervous...
Yeah sure, China is a mouse, maybe a wolf in sheep's clothing but definitely not a mouse. Nuclear War is the only thing that makes the US nervous.
