Re: Why?
They have this dream of being able to press a button and kill anyone they have taken a dislike to, with zero risk to their own people. An ultimate military fantasy where nobody can challenge them in any way without being eliminated on the spot.
And yet they still also fantasise about being the world's greatest democracy.
If they did have such a weapon it would of course rot away their remaining morality, ethics, and credibility.
It would also mean that the only way to respond to them (other than the total abject surrender of the rest of the human race) would be 'terrorist' attacks - the very thing it's supposed to defend against.
