Prominent leaders of India's freedom movement had friendly relations with the United States which continued well after independence from the United Kingdom in 1947. In 1954, the United States made Pakistan a Central Treaty Organization (CENTO) treaty-ally. India cultivated strategic and military relations with the Soviet Union to counter Pakistan–United States relations. In 1961, India became a founding member of the Non-Aligned Movement to avoid involvement in the Cold War power-play between the United States and the Soviet Union. The Nixon administration's support for Pakistan during the Indo-Pakistani War of 1971 affected relations until the dissolution of the Soviet Union in 1991. In the 1990s, Indian foreign policy adapted to the unipolar world and developed closer ties with the United States.
