Top experts reveal the only two places on Earth that would be safe during nuclear war

Security experts have shared the two places on Earth that might be safe in the event of a nuclear war.

Pulitzer Prize winner Annie Jacobsen is thought to be one of the most qualified nuclear experts around.

The American claims her books alone have convinced a number of billionaires to build bunkers in secret locations.

Speaking recently on Steven Bartlett's The Diary Of A CEO, the 58-year-old cited her book Nuclear War: A Scenario, which hypotheses that the world could pretty much end in 72 minutes if a nuclear war broke out.

And the reaction from the billionaires who read the book wasn't 'let's all get together and make sure nuclear war doesn't happen'. Shock.

Well, the investigative journalist claims a nuclear war would kill five of the eight billion people on Earth in the first 72 minutes. And apparently, there's only two places on earth that could be safe.

"There's one tiny little place, New Zealand, and a little bit of Australia," Jacobsen insisted.

She explained that when agriculture fails, 'we have a nuclear winter', which means that 'the sun gets blocked out'.

"There's large bodies up in the mid latitudes are frozen over in sheets of ice. And when you have all the billions of people dying, it's because agriculture fails," the expert said.

"And it is said by those who study this, the authors of Nuclear Winter, that there are some areas in Australia and New Zealand which would remain viable.

"But you're talking about kind of hunter gatherer type people."

She went on to reveal that a group of billionaires have told her that they've built bunkers in New Zealand.

But instead of thinking of 'how to save mankind', they were more bothered about 'how fast can I get my G5 loaded to New Zealand because a G5, a private aircraft, can take you from Los Angeles to New Zealand without refuelling'.

Why one former CIA agent is getting his family out of the US

Meanwhile, Andrew Bustamante, a former covert CIA intelligence officer and US Air Force combat veteran, told Bartlett the he no longer feels safe in the US.

Without sharing where exactly he would be heading to, the ex spy said he is 'fully engaged in relocating and immigrating with my family'.

He said he wants to 'find one of those safe havens around the around the world where we can just plug in and become part of a community and raise my children as global citizens and global citizens who are American, rather than American citizens who reject the globe'.

Bustamante initially planned to leave the US by 2030 but is currently on track to get out by 2026.
