On October 31, South Sudanese rebel leader Riek Machar entered the capitol city of Juba for the first time in two years to attend a peace ceremony. The ceremony in Juba was intended a confidence building measure toward the implementation of the peace deal. Earlier this summer, Machar and South Sudan's president Salva Kiir signed a peace deal, formally ending a civil war that killed hundreds of thousands of people and displaced over a million more.

On the line with me to discuss the peace deal is Alan Boswell. He is a senior analyst at the International Crisis Group who has been following events in South Sudan for years. We discuss the roots of the conflict, what lead to this peace agreement, and whether or not this new peace agreement can succeed.
