Your second question is also a good one. In earlier postings, we have debated whether things really are “getting worse” in Darfur and the implications of doing something dramatic (like a no-fly zone). A general rule is, when Darfur becomes the battleground for a clash of principles, then the rhetorical confrontation makes it harder to identify the right thing to do, get agreement upon it, and do it. The particular challenge we face in Sudan is that the kinds of real progress achieved are rarely if ever enough to satisfy many activists, so that western governments are under constant pressure to move the finishing line. In turn this undermines confidence in what has actually been achieved and makes implementation more difficult.
