So we can return to a world of conventional warfare amongst powerful counties? Worked out great for WWI and WWII.

Ill take nuclear deterrence any day over that hell.

“Hawking's rationale was that humankind would eventually fall victim to an extinction-level catastrophe - perhaps sooner rather than later. What worried him were so-called low-probability, high impact events - a large asteroid striking our planet is the classic example. But Hawking perceived a host of other potential threats: artificial intelligence, climate change, GM viruses and nuclear war to name a few.

In 2016, he told the BBC: "Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next thousand or 10,000 years.”

The problem with deterrence is that it works until it doesn’t.

Yeah, and without deterrence it will be a 100% chance of a variable hell of endless wars and tens of millions of casualties.

I'll bet on no one wanting their country obliterated by agitating another nuclear power.
