It's terrifying to take a step back from this and think about how much incredibly sophisticated technology had to go into ensuring that we could wipe out the human race in minutes.
And then, of course, there's all the technology handling the safety guards. Because we obviously don't want to wipe out the human race in minutes, so we have all these protocols and failsafes to ensure that doesn't happen unless it's really supposed to happen.
All for ... nothing.
Nothing, in the sense that every time Russia built more ICBMs the US had to build more ICBMs. That tit-for-tat got to incredibly absurd levels.
So all of this ludicrously complex technologies, from the missiles travelling to space, the lauching of multiple guided warheads, the safety guards and nuclear weapons, the trillions of dollars ... for nothing. All a game of "mine is bigger than yours" for strategic deterence.
Hopefully it stays that way.
