 Rusk accused Indonesia of aggression by attacking the Dutch forces in New Guinea in 1962 and believed that Sukarno had violated the United Nations charter, but was again overruled by Kennedy.In a case of "realpolitik", Kennedy argued the Dutch had no choice, but to be allied with the United States, meaning they could be taken for granted whereas he was highly concerned that Indonesia, which he called "the most significant nation in Southeast Asia", might become Communist.To improve relations with Sukarno, Kennedy decided to support the Indonesian claim to Dutch New Guinea; Rusk later wrote he felt "queasy" about the way that Kennedy sacrificed the Dutch to win over Indonesia and had strong doubts that the "consultation" scheduled to determine the future of the territory in 1969 would be a free and fair one.
