I read up on both examples. You're right. They are important. Zygielbojm's suicide was tragic. I'm not certain, however, what specific action the Bermuda Conference might have endorsed aside from winning the war. Bombing Auschwitz? Maybe they should have. Hard to say.
Also Alter & Ehrlich remind me that Stalin is never included in the criticism of the Allies's response to the Holocaust. Given that the USSR & then Russia was never a supporter of Israel perhaps it didn't serve any useful political purpose to include the Red Army in such critique.
Thank you for reading & responding.
