two suns in the sunset

In my rear view mirror, the sun is going down
Sinking behind bridges in the road. 
I think of all the good things that we have left undone,
And I suffer premonitions -- confirmed suspicions -- of the holocaust to come.

The rusty wire that holds the cork that keeps the anger in
Gives way, and suddenly it's day again.
The sun is in the east even though the day is done.
Two suns in the sunset; could be the human race is run.

-- Roger Waters (Pink Floyd) 1983
