I'm not a Libertarian, but I will give my answer, because this is the internet and you can't stop me. After the U. S declared war on Japan, Germany declared war on the U.S. So yes we should have been involved.
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.
