I and the public know What all schoolchildren learn, Those to whom evil is done Do evil in return.

It's Auden, September 1st 1939. A very strange choice.

Accurate scholarship can
Unearth the whole offence
From Luther until now
That has driven a culture mad,
Find what occurred at Linz,
What huge imago made
A psychopathic god:
I and the public know
What all schoolchildren learn,
Those to whom evil is done
Do evil in return.

I had a different post up; I didn't read carefully. As a reference it's a comparison of Israel not to the Nazis but to Hitler himself—he lived most of his childhood in Linz—and the attack on Gaza to the invasion of Poland. But it's more than a reference. Does the mixture of sadness and fatalism take the view of the aggressor?

The world is just a barrel-organ which the Lord God turns Himself.
We all have to dance to the tune which is already on the drum.

I first read M.J. Rosenberg at TPM. Both of them posted and deleted posts, for the same reasons.
