Could ask the Chinese
It's painfully ironic that just when China is making headway with its own space station program (third, permanent one to be launched soon), the ISS has found itself on the verge of being scuttled.
Unless the ISS can be made to pull through, a few years from now it'll be the Chinese space station that welcomes European (ESA), Japanese (JAXA) and other international guests.
Or, you know, ask the Chinese to please, pretty please help us out with a manned mission to the ISS to save it. Only a few decades too late, though.
