As far as I know half moon stance or hangetsu dachi is only found in HANGETSU KATA . Perhaps in your dojo or ryu the step is into hangetsu but in shotokan it's into kiba dachi horse stance in which case there are 3. 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.
