Say what you like about Trump, but I'm sure he's smart enough to know that the pledge he signed is in no way legally binding. I took exactly one course on contract law and even I know that. My guess is he just isn't that worried about it.
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.
