In 1965, Pakistan won most of the battles and the air war. However, Pakistan failed in its objective of taking Indian occupied Kashmir. As far as damage infliction Pakistan did more damage to India in that war and devastated the Indian Air Force and halted Indian army mobilization and caused them to retreat in many battles.
Personally, I think Pakistan should have continued the 1965 war as it had the momentum in the Air it could have rained down destruction on Indian ground forces even more and eventually carved out a path for Pakistani land forces to invade further to Indian occupied Kashmir. Winning the air war influences the whole battlefield.
Neutral assessments
There have been several neutral assessments of the losses incurred by both India and Pakistan during the war. Most of these assessments agree that India had the upper hand over Pakistan when ceasefire was declared. Some of the neutral assessments are mentioned below —
The war was militarily inconclusive; each side held prisoners and some territory belonging to the other. 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. Most Pakistanis, schooled in the belief of their own martial prowess, refused to accept the possibility of their country's military defeat by "Hindu India" and were, instead, quick to blame their failure to attain their military aims on what they considered to be the ineptitude of Ayub Khan and his government.
- TIME magazine reported that India held 690 mi2 of Pakistan territory while Pakistan held 250 mi2 of Indian territory in Kashmir and Rajasthan. Additionally, Pakistan had lost almost half its armour temporarily.[78] The article further elaborates,
Severely mauled by the larger Indian armed forces, Pakistan could continue the fight only by teaming up with Red China and turning its back on the U.N.
- Devin T. Hagerty wrote in his book "South Asia in world politics"[18] –
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 United Nations intervened on September 22, Pakistan had suffered a clear defeat.
- In his book "National identity and geopolitical visions",[79] Gertjan Dijkink writes –
The superior Indian forces, however, won a decisive victory and the army could have even marched on into Pakistani territory had external pressure not forced both combatants to cease their war efforts.
In three weeks the second Indo-Pak War ended in what appeared to be a draw when the embargo placed by Washington on U.S. ammunition and replacements for both armies forced cessation of conflict before either side won a clear victory. India, however, was in a position to inflict grave damage to, if not capture, Pakistan's capital of the Punjab when the cease-fire was called, and controlled Kashmir's strategic Uri-Poonch bulge, much to Ayub's chagrin.
