Yes, we must. And we must read such history through the lens of experiences like yours. The Lebanese civil war only happened because the Palestinians were taken into Lebanon. That war ended when the IDF cleaned them out of Lebanon, root and branch. This is what is required when dealing with Palestinians. They will always claim to be the victim, when they are the aggressor.
Remember that according to Hamas, they have always been at war with Israel, and the Oct 7th attack was, according to them, a retaliation for crimes against them. So reading that this is how they framed their massacre at Damour is hardly surprising. I can't imagine that you haven't noticed how the most mainstream media have framed the Oct 7th attack? Or how this was cheered on at Harvard and Yale? You haven't noticed how the IDF's war on Gaza has been reported as war crime, and on and on?
