This number counting game regarding nuclear war is completely retarded.
Let's go with this argument that 400 million Indians die and the rest survive, whist no Pakistani within Pakistani borders survives, lets go with this scenario.
Do you really think nuclear war is some kind of a virus like Covid19?
People die where they stand, or from an illness being looked after in a hospital whilst rest of the life goes on, What a stupendously ridiculous conclusion.
Every nations administrative structures are in urban areas, and they tend be centred in a small area. A bomb will destroy almost all administrative structures in a city, multiply that and you have a nation with no governing structures intact, without the means to deliver or organise anything.
Then there is damage to the water supplies,
damage to agriculture and the eco-system,
long term cost to the people who survive the nuclear explosions,
long term effects from the radiation cloud and effects of radiation on agricultural productivity.
The disruption to the economic supply system,
The effects of nuclear rain and nuclear cloud in the wider region and around the world.
The world will be trying hard to protect itself, they will not come running to save India with aid, they will be condemning whoever survives.
There is an endless list of horrendous aftereffects, here we are discussing number of deaths as if that's the only thing that will matter.
SO OK, India survives,
To give it an analogy, if India survives without arms and legs,
with just the deformed head and body, nothing else intact, then that's fine, you go ahead and survive after a nuclear war.
It is not hard to imagine what kind of survival that would be.
These people are seriously retarded.
