Go read the ICJ preliminary order and the express finding that Israel does prosecute war criminals. And guess what? It's true. The Qatari state/ pro-Trump/pro-Russia media diet you are gorging yourself on does not cover it at all.
Hamas are war criminals...in all pursuits.
No, that's not also true about Israel. You are looking at a small isolated thing, which I think you are portraying unfairly and incompletely, but fine we can disagree.
But Israel has a legitimate government that has stabily for decades provided essential services to tens of millions of people.
Glad you agree Hamas must go.
What's your plan to make that happen? How would you destroy the tunnels?
You'd do the best you could. That means ordinance and coordinated evacuations and warnings, knowing that the civilian population is going to follow Hamas around up above like one of those artic foxes stalking a tundra shrew below the snow, so they can win Martyrdom™ prizes, paid in rial, no doubt. Such disregard for their own side's civilians is unprecedented in warfare. International law is based on precedent.
