This is the kind of thinking that keeps this insanity going on forever.
You're demonstrating my point: we've lost track of "who started it" and it doesn't even matter now. It's too easy for each side to claim it's the other side's fault. They both have legitimate reasons to so it's easy to get support for those claims, too.
But I would argue that correct vs incorrect is entirely irrelevant. Nothing you or I can say can justify their actions.
The point is you would not be correct. Hamas wants to end the existence of Israel but lacks the ability. Israel wants to coexist with Gaza but Hamas doesn't want that.
You say you can match any claim I make about Hamas with an equivalent one about Israel.
I say that yes but my statement about Hamas would be factual while yours would not be because Hamas really does want to destroy Israel while Israel just wants coexistence with Palestinians. At its core Hamas is an Islamic Theocratic Supremacists group that truly hates Jews. Just read their charter.
