Indylan has the nearest proper grip on this, imo. Only those with nothing to lose would ever contemplate nuclear destruction. It's really very laughable that a functional society ..with vital resources ..means to provide much to their population and keep them happy ..would just destroy it for some assumed mythical ideology. That's the sales pitch of all sales pitches. Not that we haven't swallowed some snake oil elixir in the past, mind you. Blow hard rhetoric flows like oil ..you can pump it in any country and into anyone's tank, and it appears to work just fine.
That's not to say that the advantage of us NOT doing something would not be exploited to the fullest. It's a market share thing. Right now, we still have a trump card.
