I'd write a for loop with lots of state variables, processing each line, and use the state variables to keep track of what is going on. The condtionals ( if ) inside the for loop would make the same "questions" a human would have to do would he be parsing the file by hand.
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.
