Both governments (Israel and Hamas) are driven by an urge to seek more power by claiming land and killing their "enemies". The populace are witting and unwitting pawns of that. I am not surprised people back the Israeli government with the amount of propaganda being put forth and I'm not surprised that people who have been murdered and had their homes destroyed for decades are willing to tacitly support the only group that seems like it can fight back. Desperate people don't make rational decisions.
