Joseph Kabila, the Congolese President, took office a mere 10 days after the assassination of his father, Laurent-Désiré Kabila in 2001. Since then, he has won the elections of 2006 and 2011; however, the latter were full of irregularities, and the results were rejected by the then M23 rebels in Congo. Although Mr. Kabila’s term is set to end in 2016, elections have been delayed to early 2018, criticized by many as an attempt by him to extend his term.
