That Churchill didn't cause the Bengal famine is a patent falsehood. Churchill and his Govt's policies are to squarely blame for the Bengal famine that caused untimely death of 3 million Bengali Indians.
On that basis Churchill was worse than Hitler. Even today in India when forced to choose between the two devils, most people consider Hitler at a higher status than Churchill. There's ample research now, recently reported in The Guardian (source below) that conclusively proves how Churchill's policies caused
starvation and famine.
