In my reply above, I evoked the memory of Jeanette Rankin, who was the lone dissenting vote against the Pacific War after the Japanese attack on Pearl Harbor (somewhat analogous to the October 7th attack).

It is a natural human tendency to desire that the people who inflict pain upon others to also feel pain inflicted upon them. This has been the human condition since ancient times, and yet the most revered figures in human history have been the pacifists who consistently advocate against violence (e.g. Gautama Buddha, Jesus Christ, Lao Tzu, Gandhi, MLK, etc).
