Sukarno's motives for beginning the Confrontation are contested. Former Indonesian Foreign Minister Ide Anak Agung Gde Agung argued years later that Sukarno intentionally muted Indonesia's opposition to the proposed Malaysian state while Indonesia was preoccupied with advancing its claim to West New Guinea. Following Indonesia's diplomatic victory in the West New Guinea dispute, Sukarno may have been emboldened to extend Indonesia's dominance over its weaker neighbours. Conversely, Sukarno may have felt compelled by the ongoing pressure of the PKI and the general instability of Indonesian politics to divert attention towards a new foreign conflict.
