Could you elaborate on it ? I certainly don't think our military planners can mount a campaign to retake PoJ&K without factoring in the possible usage of N weapons by Pakistan and taking adequate precautions.
When I posed the same question to PKS, he claimed the war would be waged & restricted to only J&K. When I countered him that this is precisely the thinking by Pakistan in 1965 which landed them in trouble & that there's a possibility we'd be emulating them thereby falling in the same trap, he reiterated his earlier stance.
