As it turned out, the relationship between Puzanov and Amin broke down. Amin started a smear campaign to discredit Puzanov. This in turn led to an assassination attempt against Amin, in which Puzanov participated. The situation was worsened by the KGB accusing Amin of misrepresenting the Soviet position on Afghanistan in the PDPA Central Committee and the Revolutionary Council. The KGB also noted an increase in anti-Soviet agitation by the government during Amin's rule, and harassment against Soviet citizens increased under Amin. A group of senior politicians reported to the Soviet Central Committee that it was necessary to do "everything possible" to prevent a change in political orientation in Afghanistan. However, the Soviet leadership did not advocate intervention at this time, and instead called for increasing its influence in the Amin leadership to expose his "true intentions". A Soviet Politburo assessment referred to Amin as "a power-hungry leader who is distinguished by brutality and treachery". Amongst the many sins they alleged were his "insincerity and duplicity" when dealing with the Soviet Union, creating fictitious accusations against PDPA-members who opposed him, indulging in a policy of nepotism, and his tendency to conduct a more "balanced policy" towards First World countries. According to the former senior Soviet diplomat, Oleg Grinevsky, the KGB was becoming increasingly convinced that Amin couldn't be counted on to effectively deal with the insurgency and preserve the survival of the Afghan Marxist state.
