I am an America citizen with valid passport traveling to Spain for 10 days, do I need a visa?

None. All of them that once had it recognized decades ago what problems it might create in today's world. That is why Canada and the USA are the only two developed nations that still offer birthright citizenship.

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.
