Why would it be ‘bad’ to own a nuclear weapon? If you have a nuclear bomb in your basement it’s arbitrary to say that the very act of owning such a weapon is aggression. Assuming that the NAP is going to be followed there isn’t really any justification to unilaterally state that you can’t store a nuke in your basement.
If there wasn’t a new thread on this exact same topic every single week, maybe you would read my responses and the paper explaining this.
