Great summary, thanks.
Coincidentally, I just finished a long read in The Guardian about the Rosenbergs, whose sons I’ve written about in the context of their eventual adoptive father, the folk singer who penned Strange Fruit, which Billie Holiday popularized and which became one of the best known anthems of the Civil Rights era.
Something I keyed on in the Guardian article is that while historians are now pretty universal in agreeing Julius Rosenberg was guilty of espionage, they say evidence shows he was not guilty of the specific nuclear espionage he was charged with.
The Guardian piece is quite illuminating as a brush up on the current state of Rosenberg/McCarthyism historiography, if you don’t mind me tossing you a link.
