"[1] In the early 1980s under Gandhi, India attempted to reassert its prominent role in the Non-Aligned Movement by focusing on the relationship between disarmament and economic development.
[2] Although hosting the 1983 summit at Delhi boosted Indian prestige within the movement, its close relations with the Soviet Union and its pro-Soviet positions on Afghanistan and Cambodia limited its influence.
Relations with US strained badly under President Richard Nixon when India signed the treaty of peace, Friendship and Co-operation with the Soviet Union in 1971.
He despised Indira politically and personally Nixon ordered complete stoppage of economic assistance and supply of defence equipment to India.
United states reacted negatively, especially in light of then ongoing negotiations on the Nuclear Non-Proliferation Treaty and the economic aid the US had provided to India.
The visit of Henry Kissinger, the secretary of the state of the US, to India in October 1974, helped to bridge the gap between the two countries, Gandhi's imposition of emergency in 1975 also strained the Indo-US relations.
The support of the Soviets with arms supplies and casting of veto at United Nations helped in winning and consolidating the victory over Pakistan in the 1971 Bangladesh liberation war.
[8] India had signed a treaty with the Soviet Union promising mutual assistance in the case of war,[9] while Pakistan received active support from the United States during the conflict.
[10] U.S. President Richard Nixon disliked Gandhi personally, referring to her as a "witch" and "clever fox" in his private communication with Secretary of State Henry Kissinger.
[13] India's new hegemonic position as articulated under the "Indira Doctrine" led to attempts to bring the Himalayan states under the Indian sphere of influence.
However, Mujibur Rahman's pro-India policies antagonised many in Bangladeshi politics and the military, who feared that Bangladesh had become a client state of India.
[20] Gandhi's relationship with the military regimes was strained, due to her alleged support of anti-Islamist leftist guerrilla forces in Bangladesh.
[20] Generally, however, there was a rapprochement between Gandhi and the Bangladeshi regimes, although issues such as border disputes and the Farakka Dam remained an irritant in bilateral ties.
In 1974, India ceded the tiny islet of Katchatheevu to Sri Lanka to save Bandaranaike's socialist government from a political disaster.
[25] Nevertheless, Gandhi rejected demands to invade Sri Lanka in the aftermath of Black July 1983, an anti-Tamil pogrom carried out by Sinhalese mobs.
[26] Gandhi made a statement emphasizing that she stood for the territorial integrity of Sri Lanka, although she also stated that India cannot "remain a silent spectator to any injustice done to the Tamil community.
Gandhi's authorization of the detonation of a nuclear device at Pokhran in 1974 was viewed by Pakistani leader Zulfikar Ali Bhutto as an attempt to intimidate Pakistan into accepting India's hegemony in the subcontinent.
[32] But, the death of Nasser in 1970 and Sadat's growing friendship with Riyadh, and his mounting differences with Moscow, constrained Egypt to a policy of neutrality.
[32] Gandhi's tilt towards Moscow and her dismemberment of Pakistan was perceived by the Shah as part of a larger anti-Iran conspiracy involving India, Iraq, and the Soviet Union.
[32] Nevertheless, Iran had resisted Pakistani pressure to activate the Baghdad Pact and draw in the Central Treaty Organisation (CENTO) into the conflict.
Furthermore, they were also apprehensions in the region about Gandhi's future plans, particularly after India played a big role in breaking up Pakistan and facilitating in the emergence of Bangladesh as a sovereign country in 1971.
[36] Relations only began to improve following Gandhi's endorsement of the ZOPFAN declaration and the disintegration of the SEATO alliance in the aftermath of Pakistani and American defeats in the region.
[38] After reaching a high diplomatic point in the aftermath of Nehru's role in the Suez Crisis, India's isolation from Africa was complete when only four nations; Ethiopia, Kenya, Nigeria and Libya supported her during the Sino-Indian War in 1962.
[38] Furthermore, the conclusion of the Indo-Soviet treaty in 1971 and threatening gestures by the major western power, the United States, to send its nuclear armed Task Force 74 into the Bay of Bengal at the height of the East Pakistan crisis had enabled India to regain its anti-imperialist image.
Gandhi used to use the Commonwealth meetings as a forum to put pressure on member countries to cut economic, sports, and cultural ties with Apartheid South Africa[42] Indira spent a number of years in Europe during her youth and formed many friendships during her stay there.
[44] She also enjoyed closed working relationship with many British leaders including conservative premiers, Edward Heath and Margaret Thatcher.
