Man, you are way off reality. Indian companies are considered an arm of the western companies (which they are, as all the money and jobs came from the west). And the Russians now have a ban on using western companies, specifically the consulting organizations in energy and other sectors. So that'll be a show stopper. Other small trade based businesses will go on.
USA doesn't "jitter" because of anyone's policy. You have some grandiose ideas about India. The US pretty much developed 80% of the modern India for its own interests. If it was to "jitter" as you are suggesting, because of any reason, the funding would've stopped and you wouldn't be where you are today, PERIOD.
China and US are not foes. China is a rising power and the US sees it as a big county that may get in its way. The Chinese and the US are if anything in economic related competition. That's healthy and should go on. Chinese or the Indians or the Russians can't afford a conflict with the US. You guys will go back to 1940's, PERIOD.
Trust is a subjective term, the Nepalese don't trust India, the Sri Lankan don't trust India, the Pakistanis and the Bangladeshi's hate India, this is just around your country. I think the US doesn't trust India either but its the interest that are aligned for now and these will go away in the in the next ten years when the "true" colors start to come out. Similarly, many countries hate the Chinese but many also have China everywhere, infrastructure, ports, energy, etc, etc.
The whole I for India crap is too late. Will India be a big country and economy, no doubt about it, just take a look at 1.3 billion people. But will I for India will be like the US to the World, hell no. You'll also have C for China, K for Korea, R for Russia, B for Brazil, P for Pakistan and T for Turkey. Many of these countries may be smaller in population and / or in size, but they will have very strong economies and well balanced, modern militaries which won't let India boss them around. Simply speaking, there is the United States and then others like I,R,K,P,T (whatever country reference you'd like to put in). And India will be a big military power, it just will never get to a super power status, not for the next 50 years
