He did not deserve to be India’s Prime Minister

The best way to answer this question is to ask who else in that time deserved to be Prime Minister. The most common suggestions are Subhash Chandra Bose and Sardar Patel, Let us look at both candidates in detail. Subhash Chandra Bose had intended with the support of the Axis powers to overthrow the British Government in India. He raised an army with Japanese PoWs called the Indian National Army (INA) with the intention of invading India from Britain. The INA surrendered in April 1945. There were many claims that the Japanese assistance was not unconditional as they intended to set up a puppet government in India. As they had in China, Philippines, Korea, etc. It is hard to fathom the Japanese assisted the INA without any political motive. He was rumored to have died in 18 august 1945 in a plane crash. (The fact is considered to be controversial even in present day India). Whether he was alive or not he was not available to take over the Indian Government. Contrary to popular belief, he was in very good terms with Mahatma Gandhi and held him in high regard, the title “Father of our Nation’ was used by him first to refer Gandhi. He was also in good terms with Jawaharlal Nehru, when Nehru was jailed by the British Government. Both Indira Gandhi and Kamala Nehru were in custody of Bose in Germany. The other candidate who is popularly promoted as an alternative to Nehru is Sardar Patel. Sardar Patel was in very poor health during the time, he passed away in December 15 1950. India had become a republic on Jan 26 1950. (Nehru was sworn in on that date) . In the year that followed Sardar Patel was extremely frail he had 3 heart attacks and was incapable of holding office.
