You misunderstand me. I don't think Israel is in the right. I think they are a major power fighting an armed insurgency, and they will win. I don't think that what they will do is justified, but I believe its the same as the Americans, British, French, or any other major power would do in the same situation. This is simply how nations react to such events.
I believe that the Hamas reaction is understandable, and that Palestinians living there feel it's the same oppression and fighting back will change nothing, but that they have underestimated the levels of brutality and misunderstood low vs high intensity conflict. I believe they've taken lessons from the Ukraine war without realising the severe geographical and technological differences. I also believe they were led to believe that other groups would join the struggle, noticably Hezbollah to give them a realistic shot of 'winning.'
I believe that Israel will brutally and mercilessly react with scant regard for Palestinian well being, and attempt to root them out forever. I believe that in a 140 square mile region it's going to be one of the worst and saddest massacres in the 21st century causing untold misery. And I believe that if I was a Palestinian my best choice would be to get out now. (Even though emotionally I'd want to fight to the death.)
No, I think that ROE is for western alignment, and to uphold military standards. Not because they care about the enemy. I have never said they are 'right.'
