Warren is trying to make this about women’s rights and argue that she was executed just because she was Julius’ wife.
The following is from Wikipedia. No matter how you slice it she was guilty in one of the most serious cases of treason this country has confronted.
“In 2014, five historians who had published works based on the Rosenberg case wrote that newly available Soviet documents show that Ethel Rosenberg hid money and espionage paraphernalia for Julius, served as an intermediary for communications with his Soviet intelligence contacts, relayed her personal evaluation of individuals whom Julius considered recruiting, and was present at meetings with his sources.
They support the assertion that Ethel persuaded her sister-in-law Ruth Greenglass to travel to New Mexico to recruit her husband David Greenglass as a spy.
Other historians, though, argue that this evidence demonstrates only that Ethel knew of her husband’s activities and chose to keep quiet.”
Exactly, Julius, her husband must have dominated her. Her actions, no harm, no foul. Heck, some say Benedict Arnold was motivated partly by his wife's ambitions. Even if true, who would exonerate him based on an abusive wife.
Yes, history wouldn't support that claim. But after the fact the claim can be made. Benedict may well have been motivated to provide a suitable standard of living for his wife, Ethel may have been similarly motivated. No harm, no foul to Liz
