The casualties are piling up, with over 30,000 believed dead and 1 million+ refugees. After wars with the black and mostly Christian south, the (mostly Arab) Sudanese government is busy terrorising and ethnically cleansing the black and mostly Muslim west. Robert Corr may have written the best history and summary of the Darfur crisis in the blogosphere.
Even in such an obvious case, however, multilateralism is running into trouble:
"The United States and Britain are pushing a Security Council resolution to impose trade sanctions, but they're having trouble getting it passed. Pakistan and China, for instance, are hesitant to interfere with Sudan's oil trade, which supplies about 300,000 barrels a day to Asia, partly pumped by a Chinese company."
...oh, and don't forget all the French oil deals (France is opposing sanctions, of course, as it did in Iraq). Not to mention Russian military contracts with Sudan. Meanwhile, African nations have ensured that Sudan will keep its seat on the U.N. Human Rights Commission.
Gary Farber has more on the limited progress being made, and sums it up as "Small steps continue. Meanwhile, people die." The Washington Post looks at the EU's cynical half-measures and asks, appropriately, "how many more deaths will it take?"
If YOU want to take action, a blog/ activists' workstation called Sudan: The Passion of the Present is a fine place to start.
