No, they are accountable for the atrocities they commit, hence why some of them will be killed in the conflict in Gaza (I say some because, as I said, it’s a global network that cannot be destroyed in a ground war in one area). They should be removed as the governing power in Gaza - that is them being held accountable. That is them being shown that their way isn’t an option.
But in what world is it shocking that radical islamists aren’t going to do the right thing? I find it incredibly surprising that people expect some decency/humanity/diplomacy from the people who planned and executed things like 9/11 or 7/10. The aim is to kill and die for the cause. I don’t think anyone has protested against AQ or ISIS after a terrorist attack: it’s pretty much a given that people in the west don’t support radical Islamic terrorism. There were plenty of anti- war on terrorism marches though.
Israel (apart from some members of the government and anyone involved in settler violence) aren’t extremists so should be held to a higher standard than Hamas. I wouldn’t put the US and AQ on the same moral footing or ISIS and the UK. We are different to them, hence why we are liberal democracies and they are terrorist orgs. So yes, Israel are responsible for their role in all of this. Hamas are too, hence why they are being removed from Gaza. Both sides can be held accountable for their actions, held responsible for their wrongdoings and criticised for their actions. Being up against terrorists doesn’t give you a green light to act like them. And no, this isn’t just my view now Israel is involved. I had the same issue when the US tortured suspects in prisons. Western democracies either have to admit we’re no better than our enemies when we want to do those things or uphold people’s rights no matter who the enemy is.
