Allah shows to Muslims that there are many Muslims also are suffered in Syria and Iraq and of course in Burma, Palestine, china etc, and Muslims don't even care, that's why.
Do you suppose all those christians in California that are dying due to fires were killed by God due to their sect in the christian faith?... SEE?! That sounds like a stupid question doesn't it..... people die every single day due to unseen circumstances.. it was a tragic horrific event, but it by no means, suggests that Allah punished them.. you will die yourself.. does that mean Allah will punish you in the manner of your death? NO.. it just happens.
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.
