Prince Charles is not ill, at least he is not today. Prince Philip is the husband of Queen Elizabeth II. He is not King now and cannot be ever.
Charles is the son of Queen Elizabeth, and he will assume the throne and become King after the death (or unlikely abdication) of the Queen. The Queen's Mother lived until she was 102, and so it is likely that she will be Queen for a long time yet!
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.
