That's ridiculous. That's like saying the direction a car drives in is not important.As far as India, it's form of government is not that important.
That is important. It shows they could run out of food/resources, bury large numbers of people in poverty and either need global aid or start a war they don't have a shadow of a chance to win.What's important is that there are more Indians born every year than in the US, Europe, Japan, Russia and China combined (!).
No matter India's population, they have never been united, for reasons already highlighted to you by AndrewS.India will soon be by far the world's most populous entity united under a single political banner.
Only one to drag the world down for need of aid, never otherwise because Indians have never shown competency at any population level. This strategy (if it is their strategy) is comparable to an impoverished mother birthing 6 kids and giving none of them education or support hoping to beat the middle class neighbors who have 3 kids all of whom are being educated, stimulated and morally developed to the highest standards that the parents can provide.Even if they are slow and inefficient, by pure demographic power they will have huge weight in the world.
