Many people, including most Bengalis, support Bose for taking help from Japanese, on the reasoning that an enemy's enemy is my friend. Our enemy was our British rulers and since Japan was fighting the British they were our friends. So goes the reasoning.
This reasoning would have been acceptable if there was the slightest possibility that if the Japanese had defeated the British they would have given freedom to India. But there was no such possibility.
If the Japanese had defeated the British they would not have given us freedom but would have turned India into their colony and ruthlessly looted us, the way they looted Korea, Manchuria, Vietnam, etc The Japanese were fascists, like the Nazis, and if we had resisted or opposed them in the slightest way, they would have massacred us, as they massacred people in Shanghai, Nanking, etc ( see on Youtube about Shanghai and Nanking massacres. So the theory of enemy's enemy is our friend is totally inapplicable to the context.
Bengali Babu, Jaago. Kab tak jhaanse mein rahoge ?
