I guess that has something to do with the fact that
Netaji Bose, the freedom fighter who was a widely popular figure in India during his lifetime and who wanted to exploit the weakness of the British during World War II and remove them by force from power, sought strategic help from Hitler and Tojo in his struggle against Britain after being snubbed by Russia and established the 'Provincial Government of Free India' comprising of Andaman and certain parts of north-east in the 1940s with their support. So Hitler always had 'some' India connections if you ask me. Just saying, not that I am fond of Hitler like the 'young Indians' of your link (though I morally support what Bose tried to do).
