There is a product that you can purchase to make the rear speaker wireless but they are also expensive. Those wireless speaker system can be interrupted by other electronic device in your home. You do not see any wireless system in the very high end of the audio.
I would not spend that extra money to make your rear speaker wireless. Best Buy carry the product and it is around the $200 range. Hope this will help you out.
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.
