Sino Indian War: Mutually Benificial Proposition

can war be mutually beneficial? yes.
India and China share a problem. Population.
Since they can't kill off their own population, they might as well do it for each other.
They can agree to go to war, on the condition that no nukes are used, and soldiers don't shoot at soldiers. Instead, they can exchange lists of population centers and send missiles and bombs across to those centers.
If this war can bring down the population which is over 1 billion in both countries to say 100 million or so, the result will be phenomenal. Their food and energy requirements will go down, and they will turn into exporters of things that they would have been importing.
Of course, the trick would be to hide this strategy from the world, which is not possible now that I have blogged about it.
