I need help with how to write a thesis statement or an essay.?

I think you need to do more research. Can you support that it has (significant) power today? What about the wrongly named "Black Lives Matter?"

GOOD lives matter.

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.
