PKI support of Sukarno, the influence of Sukarno's government was significantly influential and powerful. The PKI controlled several pro-government groups, expanded influence in rural areas, and possessed significant military strength. The opposition movement provided a reason for the PKI to strengthen ties and gain influence over Sukarno, thereby bolstering Sukarno's efforts against the opposition, and increasing the schism between Sukarno and western interests.
