We know God allows who he wants into heaven.. we have no right to say who will or wont.
Allah had sent prophets and messengers to every nation for example Moses pbuh was sent to Jews if those people followed the teachings of Moses pbuh (Torah) at the time they will enter paradise. Likewise the Quran was sent as the final testament and was given to the final messenger Muhammad pbuh, the message and the messenger weren't just sent for the Muslims but for the whole of mankind . Quran recognizes and confirms all previous prophets and revelations,if you analyse,the message was consistent in all the scriptures and all the prophets of God taught the same message that is to "believe in One God".
So believing in one God is essential,besides believing in one God muslims also believe in all the prophets and all the revelations and the final prophet and final revelation. So as muslims, we don't say we are guaranteed paradise ,we say we are striving for paradise and we are hoping to get the. We are no one to decide or say who goes to paradise or who don't because in the end its the mercy of Allah that will let one enter paradise.
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.
