If a nuclear war were to occur, the best way to survive would be to find shelter as quickly as possible.
This could include a designated fallout shelter or a basement or underground area.
Once in shelter, it is important to seal any cracks or openings in the shelter to prevent radioactive fallout from entering. It is also important to have a supply of food, water, and other necessities in case of a long-term stay.
Additionally, staying informed through official channels and following evacuation orders, if necessary, can also increase chances of survival.
