W.G.Ewald,
You should have come to indian forums when bush was the president, when the indo-US civil nuke deal happened and should have seen for yourself how pro-US could the indians be. When our PM was full of praise for bush and said India loves bush, he wasn't off course by a big margin, I believe PM is yet to develop that sort of rapport with Obama still, though Obama does come across quite courteous to the PM and the PM reciprocates that, what could also be said is bush took extra interest in developing relations with India and that increased the expectations on part of India way too much than should have.
When Obama took to office and things like G2 after bush having invested a lot on indo-US relations, Obama making a visit to SE-asia which prominently figured japan and china and not India, Obama telephonically calling up 20 world leaders and not the PM were all played up big time in the media and didn't go down well at all and there was a big swing in the perception, not so much towards the US, but certainly towards the Obama administration.
Obama administration tried to buck the trend and make amends by first hosting PM on the first ever state visit under his presidency but by then the expectations had taken such a beating that not many were taking this more than symbolism at best, with little substance, which is what it was portrayed as in the indian media. The real change came in post the Obama visit last year, since there has been a change in perception and outlook towards the US.
One good thing Obama has done is, he has brought down the expectation levels, which was a must for this relationship to prosper, which will take its own sweet time, since we Indians take our own time to new things, new ideas.
As far as ICBMs that can target the US main land and subs which can loiter in the high seas near the US, well times change, so do interests. India and the US not so long back were in the opposing camps, hurriyat conference being created or insurgency being supported in kashmir in the name of freedom struggle arent too much of a distant memories for indians to get over with, who knows what tomorrow has in store, so the motto is to be ready for any eventuality. All it will require is a hard nut as the president of the US and another hard nut as the PM here and divergent indo-US interests as is happening with sino-US relations today, and US then looking to create a counter weight to India, though for the next 2 decades I don't see why India needs to be as aggressively pursuing opposing interests, for now we need to talk out our differences and sort them out, which we anyway are.
One thing is for sure, with the way the indian foreign policy is now being framed, if not in a decade's time but certainly in two decade's time India will quite aggressively pursue its interests, things that might not be of interest to other world powers and for the immediate and for the next two decades india will never be a UK, or a japan, or a pakistan to the US, if it is so perceived.
