Given how close we came to all our nuclear war on at least two occasions I don't think that was necessarily a bad prediction.

Edit: the two occasions:

Indeed. Nuclear proliferation is an increasing problem, and while we now lack the superpower standoff where a war could destroy most of humanity, many states are now capable of blowing up a large chunk of the world.

It's probably only a matter of time.

It's more like the prediction that by 1950 there would be so many horses and buggies that the streets of London will be knee-deep in horse poop.

Also it's not a prediction, it's more of a soapbox.

Or the Y2K bug.
