I am sorry to say that credibility of APJ Kalam is more than any others again doesn't appear a logical point. I am from academic fraternity and I know about his scientific achievements from the people of my institute (IISc, Bangalore). So, I don't certainly believe that his is the most credible voice. At the most his opinion can be taken at the same footing as the others that I mentioned.
You are right. Todays world order allows lot of Indians to work abroad and earn a lot of money. But, please remember that still this number constitutes a meagre 1% while the industrial and neo-liberal policies of these Western countries did havoc on commom Indians(please check facts in UN human development reports, report by Swaminathan et al. and many other available) in last 20 years. So, difficult to say that whether India should be truly grateful to them or not. Clearly, their aim is not to help India but to protect their own interest. So, when these two matches, some Indians gain, but where they don't, a lot of Indian suffers.
Aligning with Russia, USA or China is not the question. Every country observes only their interest and that's natural. Our job is to see which alignment helps us the most. Unfortunately, the history doesn't speak too well for USA which is by far the most brutal among all these in last 100 years. So, I will always take it with a pinch (actually a very big pinch) of salt.
So, I just return your comment. Think rationally and honestly..
