 Kapuuo objected on the grounds that the Ovambo (who made up the majority of members of SWAPO) had not been dispossessed of their land under German and South African rule as the Hereros had, and were therefore relatively privileged newcomers to the country's independence movement.In 1974 the National Convention broke up and Kapuuo participated in the Turnhalle negotiations, as a result of which NUDO joined the Democratic Turnhalle Alliance.Kapuuo was assassinated by
an unknown assailant in 1978.
