As a Hindu I've done research on it myself. It has become popularized in the time as being a symbol of good luck, good fortune. Which is just as it is still used in Hinduism today.
In fact my ishtadev (personal name/form of God) is usually associated with the symbol...my ishtadev is Ganesh (symbolizes God removing obstacles for the devotee). Add this notion with the popularized theory at the time that Aryans had invaded northern Indian and were most likely Germanic peoples (of which this theory is now considered questionable by archeologists who have found no evidence that north India was ever invaded by peoples in ancient times and that the Aryans are the north Indians and have been right there as they always have been and the Dravidians in the south have been right there were they've always been....atleast that's what the scientific evidence is now revealing...lots of books on the subject if you ever want to read it). So since the "German" people were supposedly the Aryans and the ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
