Neither India nor Pakistan has either the geographical distance that the US and ussr had from each other, nor the prolonged period of time they had to learn from their experience of innumerable false warnings. At the beginning of the Cold War, the superpowers had many hours to determine the truth and falsity of warnings. In the '60s, their icbms flight time still allowed for 25-30 minutes to react to alarms. When in the '80s some missiles were deployed off each other's coasts allowing 10 minutes flight time, both countries had accumulated years of experience in dealing with each other's arsenals and with deficiencies in their own warning systems. They had agreed to dozens of cbms, crisis-handling protocols and procedures. However, once missiles are deployed, India and Pakistan will from the beginning have much smaller time margins for correcting error. India, Pakistan, and China all have contiguous borders. Flight times are short, especially between the former. Finally, domestic unrest can produce detonations, accidental or otherwise, in a variety of scenarios from faction fighting within the military to civil strife in the country. If there's one obvious lesson to be learnt from the Cold War stand-off, it is that the likelihood of use of nuclear weapons is always greatest between adversaries in a wartime or near-wartime situation. If the country that has nuclear weapons feels its territorial survival is endangered even by opponents who do not have nuclear weapons, the possibility of use also becomes greater. In any such face-off between nuclear rivals, which also have a history of wars between them, matters become even more fragilely poised when one side perceives itself to be strongly 'disadvantaged' in regard to the nuclear and military balance. This is precisely what Pakistan feels vis-a-vis India.
