FAIL-SAFE

I, too, remember the "duck & cover" and "air-raid drills" from elementary school.
I also remember that frightening film we kids were made to watch instructing us as to what to do in case of a nuclear attack.
As if that would have done any good!
If the blast itself didn't kill us, the effects of radioactive fallout would.

I can remember my friends and I being really scared at this time.
Of course, this was during the peak of the McCarthy era, where there was a "Commie" behind every bush.

Thank God those days are over!
Although there is still danger here in the US from terrorist attacks, especially from Muslim extremists, such as ISIS.
Never forget 9/11/01!
