From 1973 until the PDPA unification in 1977, Amin was second only to Taraki in the Khalqist PDPA. When the PDPA ruled Afghanistan, their relationship was referred to as a disciple (Amin) following his mentor (Taraki). This official portrayal of the situation was misleading; their relationship was more work-oriented. Taraki needed Amin's "tactical and strategic talents"; Amin's motivations are more uncertain, but it is commonly believed that he associated with Taraki to protect his own position. Amin had attracted many enemies during his career, the most notable being Karmal. According to the official version of events, Taraki protected Amin from party members or others who wanted to hurt the PDPA and the country.
