Over the past ten days or so the government in Khartoum has taken a series of steps to translate its consequently racist nationalism into law. The National Assembly approved in principle a set of amendments to the Nationality Law that strip any South Sudanese in the North of the nationality of the rump Sudanese state. The legislators of the National Congress Party (NCP) more or less challenged each other in their demonstration of chauvinism. One of them demanded that the amendments clearly refer to the Referendum Law, the article of legislation that governed the referendum on the future of South Sudan in January 2011, as the basis to define who is a Southerner.
