Quite ahistorical for DoD to suggest that the "nuclear triad has kept the peace since nuclear weapons were introduced."

Not only did the modern "triad" take decades to form, but it also wasn't inevitable. It largely resulted from inter-service rivalry––not strategic planning. https://twitter.com/nukestrat/status/1334582318971891712

The way that DoD often talks about the "triad," you'd think it was created by a bunch of generals sitting in a room in 1945 trying to think up *the best* deterrence posture.

I really like Donald MacKenzie's characterization of how the triad was created over time:

"The United States built its missile arsenal without any agreed understanding––even within élite circles, much less among the general population––of why it was doing so.”
