Is there anything you can really do to prevent nuclear war?
If nuclear power goes unhined enough to press button out of “apres mois, le deluge”? Absolutely nothing. First strike wont work because US have significant second strike ability. They have 450 land based ICBM’s launch sites and 14 ICBM armed submarine, this is basically not possible to neutralise unilaterally by any means.
The United States’ inability to acknowlege reality will convince them to make tactical blunders in their own hubris.
They are already doing it, and as their position worsens, those blunders have increasing consequences, like the Ukraine War activating the spiral of dedollarisation. So that’s positive since it will bury them eventually, i just fear the last blunder might be nuclear and it will bury us all.
