roberts has always believed that real changes could only be brought about with non-violent means and so did not agree with the attitudes of anc (african national congress) and pac (pan africanist congress) in this point. during the 1980s, when the country became more and more insecure and violence increased, including the infamous practice of “necklacing” , roberts organised several peace conferences together with bishop tutu where they tried to bring  together the various hostile factions  and find a solution to end the violence.
