Indo-Pakistani War of 1965

The Indo-Pakistani War of 1965 was a culmination of skirmishes that took place between April 1965 and September 1965 between Pakistan and India. The conflict began following Pakistan's Operation Gibraltar, which was designed to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against Indian rule. India retaliated by launching a full-scale military attack on West Pakistan. The seventeen-day war caused thousands of casualties on both sides and witnessed the largest engagement of armored vehicles and the largest tank battle since World War II. Hostilities between the two countries ended after a United Nations-mandated ceasefire was declared following diplomatic intervention by the Soviet Union and the United States, and the subsequent issuance of the Tashkent Declaration. Much of the war was fought by the countries' land forces in Kashmir and along the border between India and Pakistan. This war saw the largest amassing of troops in Kashmir since the Partition of British India in 1947, a number that was overshadowed only during the 2001–2002 military standoff between India and Pakistan. Most of the battles were fought by opposing infantry and armoured units, with substantial backing from air forces, and naval operations. Many details of this war, like those of other Indo-Pakistani Wars, remain unclear. India had the upper hand over Pakistan when the ceasefire was declared. "Satisfied that it had secured a strategic and psychological victory over Pakistan by frustrating its attempt to seize Kashmir by force, when the UN resolution was passed, India accepted its terms... with Pakistan's stocks of ammunition and other essential supplies all but exhausted, and with the military balance tipping steadily in India's favour." "Losses were relatively heavy—on the Pakistani side, twenty aircraft, 200 tanks, and 3,800 troops. Pakistan's army had been able to withstand Indian pressure, but a continuation of the fighting would only have led to further losses and ultimate defeat for Pakistan." Quote: The invading Indian forces outfought their Pakistani counterparts and halted their attack on the outskirts of Lahore, Pakistan's second-largest city. By the time the United Nations intervened on 22 September, Pakistan had suffered a clear defeat. Although the two countries fought to a standoff, the conflict is seen as a strategic and political defeat for Pakistan, "... the war itself was a disaster for Pakistan, from the first failed attempts by Pakistani troops to precipitate an insurgency in Kashmir to the appearance of Indian artillery within range of Lahore International Airport." – U.S. Department of State, – Interview with Steve Coll in United States House of Representatives 12 September 1994South Asia in World Politics By Devin T. Hagerty, 2005 Rowman & Littlefield,, p. 26 as it had neither succeeded in fomenting insurrection in Kashmir "... after some initial success, the momentum behind Pakistan's thrust into Kashmir slowed, and the state's inhabitants rejected exhortations from the Pakistani insurgents to join them in taking up arms against their Indian "oppressors." Pakistan's inability to muster support from the local Kashmiri population proved a disaster, both militarily and politically." nor had it been able to gain meaningful support at an international level. "Mao had decided that China would intervene under two conditions—that India attacked East Pakistan, and that Pakistan requested Chinese intervention. In the end, neither of them obtained." Internationally, the war was viewed in the context of the greater Cold War, and resulted in a significant geopolitical shift in the subcontinent. Before the war, the United States and the United Kingdom had been major material allies of both India and Pakistan, as their primary suppliers of military hardware and foreign developmental aid. During and after the conflict, both India and Pakistan felt betrayed by the perceived lack of support by the western powers for their respective positions; those feelings of betrayal were increased with the imposition of an American and British embargo on military aid to the opposing sides. As a consequence, India and Pakistan openly developed closer relationships with the Soviet Union and China, respectively. The perceived negative stance of the western powers during the conflict, and during the 1971 war, has continued to affect relations between the West and the subcontinent. In spite of improved relations with the U.S. and Britain since the end of the Cold War, the conflict generated a deep distrust of both countries within the subcontinent which to an extent lingers to this day."In retrospect, it is clear that the Indo-Pakistani War of 1965 represented a watershed in the West's association with the subcontinent.""By extending the Cold War into South Asia, however, the United States did succeed in disturbing the subcontinent's established politico-military equilibrium, undermining British influence in the region, embittering relations between India and Pakistan and, ironically, facilitating the expansion of communist influence in the developing world." "The legacy of the Johnson arms cut-off remains alive today. Indians simply do not believe that America will be there when India needs military help... the legacy of the U.S. "betrayal" still haunts U.S.-Pakistan relations today.".
