This is something very worrisome.
Because this moon landing shows China's ambition.
China isn't just trying to overtake the US, it is trying to BECOME the new US. This is the ambition at the back of their minds, even if the Chinese do not yet know it themselves.
Just look at their new stealth fighter and aircraft carrier. They are beginning to model their military after the US. They want a fleet that can sail to any corner of the world to impose China's will. Just as the US is doing now. And they are preparing to do battle on the high seas with carrier fleets, the way Japan did with the US in WW2.
So why is this a bad thing? Simply because China is not run like the US.
Right now the US is Number One, but it is no big brother. It is a military industrial nation. It can go to any part of the world to destroy countries. But to keep itself in check it has a democratic process. For example, if a president wages a war, pretty soon the people will get tired and hold protests, vote someone else, start scandals, pull wikileaks, etc. Then the politicians have no choice but to give in. The outgoing president will end his term, and the new one will wind down the war.
Or it may not even go to war, because the democrats and republicans can't reach any agreement.
In short, the US political system sucks in many ways, but it has a mechanism to limit abuse of its own power, however ineffective or crappy that mechanism is.
But if China overtakes the US and becomes Number One, there is simply no such mechanism in place. And such a world is no good for anybody, including China and its own citizens.
Yet it is almost certain one day China will overtake US to become Number One. We can only hope when that happens China has changed enough to become more like the US.
