Your question reeks of condescension. President Obama is a Harvard law graduate. He is intelligent to know what is what.
He is not "trained to know" he is human and is educated. That said he is a politician and can and does know how to have a news conference. I bet he could tell you what magazines and news papers he reads.
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.
