> If Hamas would take up a defensive stance, there would never be any conflict. The only reason Israel attacks has been in response to terrorism.
Proof that this claim is not true is the occupation of West Bank which has submitted itself to Israeli rule without violent opposition. I am sure that you have heard the long list of grievances of its population against the Israeli occupation a million times by now, so I will spare you from going much into it here (military law for Palestinians, imprisonment of children, night raids just to show force and keep IDF soldiers trained etc).
Additionally, using the "terrorism" label is fairly meaningless when the label is assigned by one's enemy that keeps the land under occupation. An enemy that has an overwhelming technological, economical and military advantage that makes a direct confrontation impossible. While Israeli airplanes and drones are leveling residential buildings from distance, they are calling shooting of primitive rockets and guerrilla-style warfare terrorism. Every occupying power in the history of humanity, ever since the word "terrorism" has been introduced into our vocabulary, has called every resistance group terrorists. Also, the countries that you named that have publicly proclaimed Hamas a terrorist groups are all close NATO allies that mostly follow the lead of USA, which in turn strongly supports Israel's position.
We can all agree that Oct 7 attack of Hamas was horrible and that attrocities were committed during which a little under 400 soldiers and a little over 800 civillians were murdered. But if you will call that terrorism, then you have to be logically consistent and call the subsequent revenge-bombing of Gaza (in order to punish Gazans and Hamas alike for striking) what it is, given the death toll, siege conditions, genocidal rhetoric of Israel's leadership, and the devastation inflicted even just in the first few weeks, before the ground offensive even began. About 4000 children were dead before the ground invasion. Children. Children are not Hamas fighters who invaded Israel. Call Hamas whatever you want, but be consistent and just when applying labels.
