I believe that the US is, via private rockets, on track to go back to the moon by 2024, and stay.
It appears to me anyway that a moon base might be more difficult to setup but more cost efficient in the long run.
The Chinese are 20 years behind. They’re thinking LEO, we’re talking about the moon. Let them put up a station. There’s so much debris in LEO, they’re going to be dealing with the same issues as the ISS, and given their terrible debris track record with Long March, a Kessler event is becoming more likely.
