Operation Gibraltar in the context of "Indo-Pakistani War of 1965"

The India–Pakistan war of 1965, also known as the second Kashmir war, was an armed conflict between Pakistan and India that took place from August 1965 to September 1965. The conflict began following Pakistan's unsuccessful Operation Gibraltar, which was designed to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against Indian rule. The seventeen day war caused thousands of casualties on both sides and witnessed the largest engagement of armoured vehicles and the largest tank battle since World War II. Hostilities between the two countries ended after a ceasefire was declared through UNSC Resolution 211 following a 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 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.

India had the upper hand over Pakistan on the ground when the ceasefire was declared, but the PAF managed to achieve air superiority over the combat zones despite being numerically inferior. Although the two countries fought to a standoff, the conflict is seen as a strategic and political defeat for Pakistan, as it had not succeeded in fomenting an insurrection in Kashmir and was instead forced to shift gears in the defence of Lahore. India also failed to achieve its objective of military deterrence and did not capitalise on its advantageous military situation before the ceasefire was declared.

Zulfikar Ali Bhutto NPk (5 January 1928 – 4 April 1979) was a Pakistani barrister, politician and statesman who served as the fourth president of Pakistan from 1971 to 1973 and later as the ninth prime minister of Pakistan from 1973 until his overthrow in 1977. He was also the founder and first chairman of the Pakistan People's Party (PPP) from 1967 until his execution in 1979.

Born in Sindh and educated at the University of California, Berkeley and the University of Oxford, Bhutto trained as a barrister at Lincoln's Inn before entering politics. He was a cabinet member during president Iskandar Mirza's tenure, holding various ministries during president Ayub Khan's military rule from 1958. Bhutto became the foreign minister in 1963, advocating for Operation Gibraltar in Kashmir, leading to the 1965 war with India. Following the Tashkent Declaration, he was dismissed from the government. Bhutto established the PPP in 1967, focusing on a left-wing and socialist agenda, and contested the 1970 general election, arising as the largest political party in Western Pakistan with a landslide victory in Punjab and Sindh; and a coalition victory with National Awami Party in Balochistan and the North-West Frontier. The Awami League, victorious with a landslide in East Pakistan, and the PPP were unable to agree on power transfer, leading to civil unrest in the east — further intensified by military action under Yahya Khan's military government — followed by a civil war and a war with India, resulting in the creation of Bangladesh. After Pakistan's loss in the east, Yahya resigned amidst a military revolt against him and Bhutto assumed the presidency in December 1971, imposing emergency rule and securing a ceasefire on the western front.
