The biggest problem is that the violence has created a cycle of revenge and fear, tinged with ethnic divisions,which will be extremely damaging for the future cohesion of the country. The longer the violence continues, the more difficult it will be to stop the country from sliding into all-out civil war.
The immediate focus now is on stemming the violence. While President Salva Kiir and former Vice-President Riek Machar have reportedly committed to dialogue, no real progress has been made, and once again peace talks were stalled on the issue of political prisoners yesterday. That deadlock does not seem to have been broken today.
On the anniversary of South Sudan's independence referendum, Kiir and Machar must take responsibility for stopping the fighting, call for restraint and commit to holding direct talks urgently.
The country cannot afford to wait for a long drawn-out political peace process. Stopping the violence immediately is the priority, alongside a serious process of reconciliation in the long-term.
While the people and politicians of South Sudan will undoubtedly be the most significant players in determining the future of their nation, international actors will also need to reflect on how to refocus their efforts to support a peaceful transition in South Sudan.
These will need to build on a sophisticated and nuanced analysis of power relations, causes of vulnerability and drivers of conflict, which must be continuously revised to be useful. Technical fixes have failed South Sudan: it's time to put politics at the heart of the nation-building project at last.
