Many of Americans, including soviet immigrants, enlisted in the army driven by that feeling.
Israelis lost significantly more of their population percentage-wise during October 7 attack perpetrated by the official government of Gaza AND as we know now, some Gazan civilians. Over 200 Israelis were taken hostage.
With that in mind, its fairly simple for me to empathize with the Israeli public who are angry at the death of their fellow citizens and want Hamas to be punished.
