An interesting find, and a sig I've not seen anywhere else online - "Make Peace or Die" from Charles U. Daly, the last living cabinet member of JFK's administration. A decorated war veteran, he worked with both JFK and Bobby Kennedy (he was the second agent to reach the latter after he was assassinated), helmed the JFK Presidential Library and was President of Harvard University for several years. A very interesting read, and a rare find, particularly because this was published in the middle of COVID and the author only did one (IIRC) speaking event during the lockdowns.
