It is quite true that a single event may change the course of the history of a nation. This is quite evident from the history of our own country. If Jaichand had not invited Gori to join his forces and defeat Prithvi Raj, Gori could have never succeeded in establishing an empire in India. Even in the modern times, the imposition of internal emergency in the country turned the course of events. But for it, non-congress parties could not have tasted power in 1977. The latest in the series is the Indo-US friendship. Had the Indian Government not made the atom bomb, the international community would have never given us the respect it is giving us today.
