I'll tell you exactly how I'd feel about that, I'd feel that you shouldn't kill innocent people from the countries that the terrorists hail from in response, because I'm not a shitty human being. Unfortunately I don't think I can say the same for you in good conscience.
You have avoided the main topic to try and make a point that is still unrelated to the topic at hand. We are not talking about helping Palestinians. I don't know how you still don't get it. You're intentionally ignoring it and it is really starting to piss me off.
You think that bombing hospitals, schools, and homes is somehow helping the Palestinians, that is all I've gathered from you. If you genuinely think this, you're insane. Those are war crimes, you cannot kill noncombatants even if it means taking out a few enemies. If you needed help with receiving food and clean water, how is someone killing you going to help with that?
Israel has shown that it does not care about the rules of conflict or setting a rule of peace and prosperity, they are no different than any of the other blood hungry countries like Russia and the US. If they are not tried for the crimes they have committed against Palestine, that should tell you everything you need to know about the world's governments.
And no, those are not all of the answers, but they are a START. If need be, martial law can be enforced until the situation is under control, there are measures that can be taken for situations like this. There are 193 countries currently in the UN, you mean to tell me not a single one can lift a finger to help out with this situation?
