While Indira Gandhi had no clear world vision based upon the study of history, she had, nevertheless, a clear perception of India's strategic and national interests. In contrast to her father, Indira Gandhi knew that in international relations power counted more than personal influence and that the strategic interests of a nation-state were far more important than moral principles. She followed pragmatic policies and her relations with the leaders of the superpowers were based upon cold calculations. She was successful in protecting India's vital interests without succumbing to the pressure of the superpowers. An increase in India's economic and military strength during her regime made India an important and independent regional power which none of the superpowers could afford to ignore.
