The US believes that a multi-polar world is inherently unstable as compared to a bi-polar world. Therefore, the US is deliberately working for a bi-polar world than multi-polar environment. However, for this to happen, they are helping to establish a balance of power at continental level in Asia and at regional levels as well within various Asian regions.
India may just be a provider of balance of power and not a pole of the bi-polarity which the world is heading towards. Robert Kaplan says it is a balance of power on steroids and that is why the expansion of Indian Navy is not being hindered by the US.
Spykeman said the domination of America in the Caribbean ensured American dominance in the western hemisphere. So if China dominates South China Sea, it will dominate the Indian Ocean and therefore Eurasia. Thats what the US with ensuring the balance of power in the region would endeavour China to not be successful with. Containment of China therefore is so important for the US though US would not want to call it containment.
The thing to understand here is that the US has a forward looking strategic partnership with India in all but name. Its not called that, but thats what it is. It can not be called a strategic partnership because the Indians demand and want to remain neutral as they were non-aligned once. They would tilt towards US as compared to China. The nuclear pact with India raised Indias stature in all but name.
I will quote Robert Kaplan here again, where he said in one of his talks in the US, that India is the only country where George Bush could go and take all his intellectuals intellectuals like George Bush.
I dont want to make it very lengthy, but all I want to say is that one does not see India, at the grand strategic level, adjusting itself to the realities as exist on ground and the US is again and again saying it very loudly. This speaks of a lack of vibrant strategic space and a culture where one only hears about how big India is going to be and not sound and sane voices telling India about where India stands now and how should India adjust itself to the ensuing future in real-politik terms.
Yes the Indians can kill me now.
