No improvement of any sort will happen anytime soon with the crisis in Darfur. Instead the situation there is bound to get worse and worse as the Sudanese government refuses to cooperate with the UN, even as Kofi Annan spoke out about possible catastrophe in Darfur.
This other BBC article highlights the problems with Darfur especially the political games that are being forced upon the UN.

However one good and sadly humorous piece of news reagarding the African Union (AU) force currently there: "However, Africa does not always follow the script. The African Union force apparently does not even have enough money to pull its troops out, so it might stay anyway and if a deal can be worked out, it might yet form part of a UN force."

The UN and world powers are heavily being pressured by advocacy groups and activists to send a force to Darfur right away, with their rationale being the terrible tragedy happening there warrants the violation of a state's sovereignty over its borders. However both logistically and politically it seems very unlikely for the West to actually do this, as the article mentions. Furthermore with the Iraq invasion and occupation, the US and Britain lost a lot of moral capital so that even oppressive governments like Sudan's can seem righteous in refusing the UN and the powers from sending in any troops.
