Last week, South Sudan government withdrew its forces from the Sudanese borders. No one knows what is behind this positive step, since Juba's military tactics are always suspicious. Last week, South Sudan government withdrew its forces from the Sudanese borders. No one knows what is behind this positive step, since Juba's military tactics are always suspicious The withdrawal is a result of the Ethiopian Prime Minister's mediating efforts to resolve escalating differences. Simply, observers deduce that South Sudan's move to harm Sudan politically and economically since secession is tactical rather than strategic despite the fact that South Sudanese government doesn't differentiate between strategic and tactical ABC. South Sudan's policies stems from accumulated resentment towards the Sudanese people and government. It dates back to 1955, but soon developed into sociopolitical. Later, the leaders of the Sudan People's Liberation Movement (before the secession) have embarked on escalating and aggravating the situations on the joint borders and bringing the war to the heart instead of the periphery as retaliatory act. More specifically, South Sudanese leaders are resentful towards the ruling National Congress for the repeated defeats they have experienced in the front during the war which ended in 2005 following the signing of the Comprehensive Peace Agreement. Although SLM has succeeded in splitting South Sudan through the referendum, it has has failed to forget the bitter defeats by the National Congress. For all these reasons, South Sudan under the ruling movement behaves recklessly with Sudan. In the course of time, South Sudan has changed its view. It is now convinced that that the National Congress is the only powerful party in the Sudanese political landscape and that the weak opposition is unqualified to replace the current government. Having the same vision, the European and US see that the Sudanese political opposition has no political future and that the ruling National Congress is only political option. Fortunately, the South Sudanese leadership has begun to understand the lesson that Khartoum under the National Congress is far better and politically stronger. They are certain that weak rulers in Sudan will constitute a threat South Sudan interests and stability.
