If you go back in history, India threw out the big oil giants - Esso, Shell, etc. They have their own oil exploration programmes. They have strategic alliances with Iran and are working on an alliance with Venezuela.
The US and British oil companies would desperately love to get back in force in India. Remember the Enron debacle started with an anti-Enron movement in India - the Afghanistan pipeline was originally to feed this Power Plant in Maharashtra.
As regards Sikhs, the people who wear turbans - they are as Indian as any others. There are a few separatists. They are some of the most hard-working people of India. The entire wheat revolution in India was due to the hard work of the Sikhs. They are excellent technicians and have contributed much in all fields from engineering, politics, education, army, etc. in the development of India.
I (personally) do not know a single Sikh who claims he is not Indian first and Sikh second. (And I know many many Sikhs.) Remember, the Sikh religion is the absolute midway between Hinduism and Islam-ism, respecting both.
Indians abroad are service oriented and that is why they are found in many service industries where they work hard and become millionaires. The corner-shop grocery store in the UK is an example where they now absolutely dominate as they work round the clock to serve their customers.
