What are the possible threats of evolving nano technology?

If any weapon of mass destruction gets into the wrong hands it will be a threat. It's not the technology that is a threat it's the people using them that are.

Nanotechnology is not only one of the future's most promising technologies but also one of the most dangerous. We still do not know enough about nanotechnology to foresee its effect on the balance of weapons of aggression versus weapons of defense. Yet it is curious to notice how offensive weapons--particularly nuclear weapons--have gained superiority over defensive weapons in the modern world's military balance, and we can expect nanotechnology to yield similar weapons of mass destruction.

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.
