How much time do we have?
Minutes, days, months, years?
We don't know
But this we do know:
Civil Defense is everybody's business

It's a big job getting Civil Defense organized; operate efficiently
But then atomic attack is disaster on a big scale
We can and must get the job done, if we ought to survive

Just imagine, if just one atom bomb was to be dropped on an American city
Say it's your city
Thousands would be killed instantly
Many would be trapped, or buried in wreckage
Streets would be blocked by rubble
Great fires would start
Dozens of fires would start in a matter of minutes, in many places at once
Then too a large part of the city's food supply might be knocked out
The water supply might be cut off
Normal communication might stop, certainly transportation would

How much time do we have to prepare?
We don't know
But this we do know:
Civil Defense is everybody's business
It's your business
