The "war" didn't start on October 7th. The genocide started in 1948 when Israel committed the Nakba, killing thousands of indigenous Palestinians and kicking more out of their homes. The reason? What they called (and still call) "Ethnic cleansing."
Ever thought of it like this:
What about October 6? October 5th? October 4th? What about all of the days before this? Israel isn't bombing Gaza because of what Hamas did, they are bombing Gaza because they want to take over the land. They just use October 7th as an excuse for this. They have been doing this for decades, and it just happened that it wasn't so public.
Just do research and you'll see whats actually going on.
In 1948 Israel kicked Palestinians out of their homes and killed 750,000 Palestinians. Why? I don't think there was Hamas then. What do you think is going to happen when you absolutely slaughter people? You think they are just going to sit there and let you murder their family?
It's because of Israel that Hamas was created. Don't you think if someone came, stole your house, killed your family, kicked you out of your land, you would just sit there and let them do it?
Hamas is just fighting back for what Israel is doing to them. And plus, is Israel that militarily weak that they have to bomb whole hospitals to kill one Hamas militant?
You said Gaza is beyond saving at this point. Whose fault is that? If Israel's only goal was to kill Hamas, then why would they refer to it as ethnic cleansing? Why would they call Palestinian humans animals? Why would they say that no one is innocent in Gaza? I know and you know that this genocide in Gaza isn't only to get rid of Hamas. This has been going on for decades.
Listen man, all I am asking you to do is just research. Just research about what happened in Palestine, the history of Palestine, history of Israel etc. This has been going on for a long time. Longer than you have been born, I'm sure.
