The 1964 satire, Dr Strangelove or: How I Learned to Stop Worrying and Love the Bomb, with comic genius peter Sellers, would be worth another look, perhaps being prophetic of modern times. It seems now that the three major nuclear powers do not hold to the strict Mutually Assured Destruction (MAD) doctrine, and certainly Russia and communist China do not, with the “escalate to de-escalate” strategy. Communist Chian seems to hold to the do anything to win position. But, he Biden administration’s Nuclear Posture Review, has now proposed that the US will use nukes, “in extreme circumstances to defend the vital interests of the United States or its allies and partners.” And, that is a wide as the Russian and Chinese positions. It means that the policies are now in place where nuclear conflict could occur much more readily than in the past, as a first strike option is now on the cards.
