Well by 1983 India was a rapidly growing, would be great power. In contrast, Pakistan's economy had stagnated for 2 decades and most of its people were subsistence farmers, making them desperate for a war to reverse their fortunes. 1979 to 1983 were the worst years for Indian democracy, Indira Gandhi had ruled for 8 years in "Emergency" because of "Partisans" (Partisans who were less in number than the North Carolinian secessionist movement, that is absolutely zero). This war in turn resulted in a bloodbath for the fanatical Pakistanis, 4 Pakistanis dead for every Indian soldier. The Indians gained 4 Puppet states and a Neutralized Pakistan, of course they lost 620,000 people and Indira Gandhi was imprisoned of in the popular revolution during the war, ultimately the army was tired of Gandhi's incompetence and allowed her to be imprisoned. Next, the army swiftly took over Pakistan's major cities. All this means that the war would have been inevitable.
