Rotation is relative to the parent, and when you rotate the parent object it will change the frame of reference for the child. This doesn't matter when you are only rotating around one axis, but makes a difference when you rotate around two. To undo the rotations, you have to undo all of them, in the reverse order that they were applied.

Try it with a book, or your phone, rotating by 90 degrees on one axis, then a second. You can't get back to where you started and you will always have involved the 3rd axis.
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.
