Countries that can survive if an all-out nuclear war breaks out

The researchers estimated that if a nuclear war broke out between Russia and the United States, it would be devastating not only to the peoples of the two countries but to the rest of the world, killing 5 billion people due to global famine, estimating that few countries could survive this, especially Australia.  

In a research paper published in the journal Nature Food, the study, which was reviewed by researchers, said that a full-blown nuclear war would threaten food security and starve billions.

The paper said that the soot from a nuclear exchange released into the atmosphere would be enough to block the sun and prevent crops from growing, and temperatures would also drop, sending large swaths of the world into a so-called nuclear winter.

As part of the study, the researchers tested climate models simulating six different scenarios of nuclear war to determine what would happen to agricultural production and trade, one of which was a large-scale war between the two powerful nations of Russia and the United States, and they found that in this scenario, more than 75% of the world would starve in within two years.

All countries except Australia and some countries in Africa and South America will be affected, and it also modeled what would happen to agricultural production and trade in a relatively small nuclear war between India and Pakistan.

In this case, the result would be catastrophic as more than two billion people could die as a result of starvation.

Significantly low yields can be seen in the high mid-latitude countries, which include the United States and Russia which both export goods to dependency-dependent countries in Africa and the Middle East.

Much like what happened about 66 million years ago when a space asteroid wiped out about three-quarters of all species on Earth, many of those not directly affected by the impact would have succumbed to starvation.

The researchers suggest that nuclear war would have the same grim outcome.
