However, the more important issue is not to get distracted by these sort of things. We can tit-for-tat this endlessly and never get anywhere, and the only way to solve this is to move beyond that. That's what they did in NI.

If we strip away all the violence, forget who did what to who, and all of that, then the inescapable conclusion remains: the IRA was right to protest the treatment of Catholics. Even Ian Paisley later admitted as much. And similarly Hamas is ... right to protest the treatment of Palestinians. That does not mean I condone the violence, like the general rhetoric of Hamas, or anything else. It's just an acknowledgement that 1) at the core of an issue are genuine grievances, and 2) as long as these grievances exist there will always be a Hamas.

You don't need to like these facts to accept it exists. You also don't need to just shrug and do nothing about Hamas. But you DO need to actually solve the rot cause (while you're also fighting Hamas). And for decades Israel has not just flat-out refused to do almost anything, it generally has made things worse. The violence of Israel is not as spectacular as the violence of Hamas, but it absolutely exists.
