The poem itself is Auden's 1952 reworking with the Cold War and nuclear annihilation as an implicit backdrop. It reminded me of Simon Weil's Iliad or the Poem of Force.
This really captures that imho.
The speaker (I believe a professor) makes some very compelling connections between the Iliad and gang culture. It gave me a new way (but certainly not definitive) way think about the Iliad. If I recall, he may also discuss PTSD towards the end.
