Not good. Not at all. India back then was a bit cozy to the Soviets, and we favored the Pakis. But letting them go nuclear will be a growing problem.
The CIA at the time was operating under severe restraints placed upon them by the Church Amendment, which was designed to hobble and handicap all these “adventures” by the “spooks” over at the Company. But even then, that was not as bad as it got later on under the regime of the “Former Occupant of the Oval Office, 1993-2001”.
1984 was a different era, confronting communism was more important than islamofascism.
Consider what was going on in Afghanistan at the time. Pakistan was our base for supplying the Mujahadeen against the Soviets. I agree that in retrospect it looks bad, but at the time India bombing Pakistan would have really been to the Soviet’s benefit since it probably would have touched off another Indo-Pakistani War leaving the Soviets a freer hand in Afghanistan.
