The current ISS is in a poor orbit to
please the Russians and produces very little real science.

Here's a clue for you since you seem to lack one;

It's quite common for unfinished facilities to produce very little of
their intended end product.

Yeah BUT ISS is never going to produce much science return, it and the shuttle
are co dependent on one another too.

The best thing that could happen is scraping both programs and moving on.
