Obviously independence is something to be happy about, but in this case of Sudan, it seems that it was in western interest in splitting it , so they can have a Oil supplier and create a fresh new conflict. This will ultimately make Southern Sudan a Land locked stated which means it will probably have build diplomatic relations with Eritrea, so it can have access to the red sea. This will make the GDP of Sudan split. In the short time this will be a party, but in the long run it has many obstacles such as building the capital and making allies.
