Golwalkar could only write based on what he knew in 1939, not what he didn't know
Yes, Golwalkar failed to understand how evil Nazis were
But the whole world gathered at Evian in 1938 and also failed to understand how evil Nazis were!
Should historians not give this context?
Golwalkar sitting in India is supposed to know more about Europe than all the world powers : USA, UK, France, etc at the time?
Which historian does not blame the inaction of European countries for the rise of Nazi Germany
