The End

Yahoo! News - Killers: Beheading Avenges Prison Abuse
I think this will be the end, the final straw for Americans. I think they will say, to hell with Iraq. We're not going to take it anymore. Not another dime. Not another soldier. I think they'll say, we came to give you liberty and you should have been grateful but you shot our boys and blew them up and burned them and now you beheaded this nice boy who never did you any harm, so to hell with you all.
They left Vietnam defeated, in an undignified scramble from the embassy roof. They'll leave Iraq because they're pissed off, not remembering or caring that the mess is their own fault, just wanting to be rid of it.

Once again, it all puts me in mind of The Second Coming
TURNING and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

Surely some revelation is at hand;
Surely the Second Coming is at hand.
The Second Coming! Hardly are those words out
When a vast image out of Spiritus Mundi
Troubles my sight: somewhere in the sands of the desert
A shape with lion body and the head of a man,
A gaze blank and pitiless as the sun,
Is moving its slow thighs, while all about it
Reel shadows of the indignant desert birds.
The darkness drops again; but now I know
That twenty centuries of stony sleep
Were vexed to nightmare by a rocking cradle,
And what rough beast, its hour come round at last,
Slouches towards Bethlehem to be born?
