There’s clearly no justification for the murder of civilians. And it’s not a black and white issue, but Israel has to accept significant responsibility for this, Netanyahu more than anyone.
Oppression breeds hate, and it’s very difficult to argue that Palestinians haven’t been oppressed. A significant portion of the international community recognises this, but Israel can’t be held accountable because the US constantly vetoes any proposal deemed detrimental to Israel at the UN. That’s not a reflection of a fair system.
Its a depressing situation and there’s a very real risk of genocide occurring here imo, but it’s not a surprising one. There’s no justification for defending Hamas’ actions, but it’s been coming for a while.
