This is a perfect example of what I was saying in my post yesterday. Given that any space program is going to be a large scale, multi-year (possibly multi-decade) effort, how do you accomplish anything when it is tied to the constant budgetary and political bullshit that infects our governments? Without the ability to define programs which are immune to political tides, it is virtually impossible, and the ISS is prime example.
As long as we have few if any leaders in the world who have any vision beyond the next election and their own (very well financed) retirements, there is no hope for space exploration.
The only hope lies in non-governmental space exploration.
