I get the impression that Pablo Neruda's last work was not widely distributed in the USofA.
A Call for the Destruction of Nixon And Praise for the Chilean RevolutionI don't think this is widely available even today. I have found a copy published by West End Press in 1980, translated by Teresa Anderson.
from Neruda's "Brief Explanation"
This is an incitement to an act never before seen; a book dedicated to poets ancient and modern, dead or alive; we are putting a cold and raving perpetrator of genocide against the wall of History.
In this book there takes place his arraignment, trial and possible final disappearance, caused by heavy poetic artillery, sent into action here for the first time.
...
I make no excuses: Against the enemies of my people my song is offensive and hard as Araucanian stone.
...
Steady now, I'm going to fire. -- Neruda, Isla Negra, January, 1973
And fire he does, invoking Walt Whitman at the outset, while "the paper flies up and the pen is unsheathed."
The Judgment
Summoned by me the entire earth
that fits, as you will see, inside my sonnet
will deliver the judgment of spring,
face to face, looking at your skeleton,
so that never again will any mother
bleed into the razed earth--
carrying in the sun, under the sad moon,
a child whom I raise up like a sword,
sister-comrade, over the neck of Nixon.
A masterful poet raging against the dying of the light.
Awesome!
