An excerpt from Ramachandra Guha's book India after Gandhi.
Well, I found it extremely hillarious, probably truthful, but hillarious!
Had Shastri lived another five or ten years, it is highly unlikely that Indira Gandhi would have ever become Prime Minister and it is certain that her son would have never occupied that office.
Had Shastri been given another five years on Earth there would have been no Nehru-Gandhi dynasty.
Had Shastri lived another five years Sanjay Gandhi and Rajiv Gandhi would almost certainly still be alive.
Sanjay Gandhi would be a failed entrepreneur and Rajiv Gandhi a recently retired airline pilot with a passion for photography.
Finally, had Shastri lived another five years, Sonia Gandhi would still be a devoted and loving housewife and Rahul Gandhi a middle level manager in a private sector company.
Later, Guha said in an interview "In my view, they would have been happier and India would have been happier. They would not have lost so many members of their family to accident and tragedy. They would have a lived a quiet contented family and India would have been a better run place." Can't say I disagree...
