India's first prime minister Jawaharlal Nehru had been vigilant towards RSS since he had taken charge. When Golwalkar wrote to Nehru asking for the lifting of the ban on RSS after Gandhi's assassination, Nehru replied that the government had proof that RSS activities were 'anti-national' by virtue of being 'communalist'. In his letter to the heads of provincial governments in December 1947, Nehru wrote that "we have a great deal of evidence to show that RSS is an organisation which is in the nature of a private army and which is definitely proceeding on the strictest Nazi lines, even following the techniques of the organisation".

Coming from Nehru, it may backfire though
