One of the most comforting things about the sidelining of space exploration, in my opinion, is that it's out of the public eye.
Since nobody except a few space-visionaries cares much about the ISS (about 7 of 10 of people I know don't even know it exists) it is kind-of immune to the vagaries of political relations. I say "kind-of" because if things get really bad the treaty of co-operation might get torn up as a last diplomatic resort. I don't think we'll ever get to the point where the opposing sides are trying to sabotage it. Even the dreaded Putin-Medevev combo would never go that far. Only President Palin would do it. Let's all pray for John Mc Cain's health and well-being.
Jokes aside, I think the crews of the ISS will go on cooperating happily as long as the media forgets that the station is there.
