If you're from Asia or India it's usually a mandatory 6 month proof of quality and continual work. The one hub you've written is poor quality and has poor grammar and use of English. You won't make more than a few cents for the first few months anyway.So if you can get someone to edit your hubs and write quality content, you may get approved in future.
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.
