Do Fallout Shelters Still Exist?

In the 50s and 60s, at the height of years of nuclear war, there were thousands of fallout shelters. They were loaded up with non-perishable food and other items for survival in the event of an attack by a foreign enemy. Fallout shelters are still in existence like the one Inside Edition visited beneath a library in Passaic, New Jersey. The war between Israel and Iran has many Americans on edge. The phrase "World War III" is trending on social media.
