The actor, Richard Burton, in preparing to play Churchill, read of and said, "What man of sanity would say on hearing of the atrocities committed by the Japanese against British and Anzac prisoners of war, 'We shall wipe them out, every one of them, men, women, and children. There shall not be a Japanese left on the face of the earth?' Such simple-minded cravings for revenge leave me with a horrified but reluctant awe for such single-minded and merciless ferocity."
In this light, your question seems poignant. What might the Rambam have done, especially considering how he had to serve his master and patients in various manners and ways? As to the Russia/Ukraine conflict, which is more Amalek?
Very interesting points. What Churchill said and did after atrocities were committed against Englishmen by a vicious enemy is not analogous to where we are right now. We are on the outside looking in.
Rambam, a Court physician, was not dealing with geo-political problems as the leader of a World Superpower confronted by a powerful rogue state. His problems were much more parochial, limited to his personal role and his concerns for the welfare of a small minority community in exile.
Me, I go with Germany as the primary candidate for Amalek, but those Rooskies and Kossacks both give a run for the money. Sort of reminds me of the Iran/Iraq war when we hoped both would win.
