It's probably true that Netanyahu funded Hamas for cynical reasons. The Israeli right-wing coalition definitely needs to go. But you can't justify Hamas terrorism againsr civilians because the Palestinian people are angry and oppressed. Hamas has agency. They aren't some inexorable force of history. They choose to be terrorists. Hamas was already a radical terrorist organization in its own right, and was duly elected by the people of Gaza as such. Fuck those raping terrorists.
All this back-and-forth revenge is, of course, just a vicious cycle and shouldn't continue. But I am a little tired of this faulty reasoning that Israel is the bad guy just because they are more powerful. Palestinians and Israelis have both done things to provoke violence and both sides have, at various times, rejected peace and compromise. But Hamas is unambiguously a terrorist group that stokes division and whose sole purpose is to eliminate Israel. Hamas is a barrier to peace and will get no sympathy from me.
