Based on a recent news story about a man who shot footage of an armed drone he'd built, that would be a federal offense. Apparently, arming a drone with any type of weapon is illegal. Also, the FAA would consider it a violation of their regulations, which "prohibit the careless or reckless operation of a model aircraft."
I understand that you wouldn't create it to be a dangerous weapon designed to harm anyone. But federal authorities would take it much more seriously. They're very concerned about the development and eventual proliferation of armed drones.
Of course, if you never reveal its existence to anyone you could get away with it.
Just don't be dumb enough to post a video of it. It's not really "illegal". It's just something that the gov't will make an example of you for to scare the public from creating weapons that could give the gov't trouble when SHTF.
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.
