I agree with alanabit's polite request to the GUEST who started this thread. And to whoever posted the four other GUEST (unlabelled(posts), who may of course have been the same person. Just to allow people to know whether there is one line of reasoning or five already, adopt a label, PLEASE. It's not a question of wanting to know who they are.

History never repeats itself, but the Roman Empire probably gives a hint of what will happen...

For the end of the world was long ago,
When the ends of the world waxed free,
When Rome was sunk in a waste of slaves,
And the sun drowned in the sea.

When Caesar's sun fell out of the sky
And whoso hearkened right
Could only hear the plunging
Of the nations in the night.

When the ends of the earth came marching in
To torch and cresset gleam.
And the roads of the world that lead to Rome
Were filled with faces that moved like foam,
Like faces in a dream.

(From The Ballad of the White Horse , by Chesterton.
