I am going to join the Marines no matter what...?

Yes. It will matter for the rest of your life. If you complete USMC Boots and Infantry training, you will be ready for anything.

I suspect your question is not very clear...

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.
