Try wp_list_categories . It exports the categories from a taxonomy with links to the depth of your choosing. (so as many children categories as you want) formatted as a list (e.g. With ul and li elements).
I would add this where the menu you want to replace would go in your template. Hope that helps, but I'll come back and be more specific if it doesn't. I forgot to mention that the pages that it links to go to category pages.
See here.
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.
