American is a nationality. America and American is not a shortened version of the North America. It is a shortened version of the United States of America. Mexicans, Canadians, Columbians, Argentineans, etc. do not refer to themselves as "Americans". If they needed to refer to the continent they are from, which would be extremely rare, they would say "North American" or "South American".
However, in all the years of my life I've never had to refer to myself by my continent. I would say Canadian... and if someone was too dim to know what continent I was from... I wouldn't be expecting much of a conversation. If I need to explain to a three-year old where Canada is... I would just say, "That's in North America".
If you call a Canadian an "American", you'll get either a strange look or rather negative reaction.
Technically everyone in the Americas (North America, South America, Central America, the Caribbean) is American. Canadians, Chileans, Brazilians, Jamaicans, Bahamians, Mexicans, Nicaraguans, Panamanians, Colombians, Guyanese... (etc.) are all American.
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.
