Once again, you apply a set of standards that isnt applicable and you imply that ROE (which can change) is law of war. You are incorrect on both counts.
The laws of armed conflict apply to uniformed military, not unlawful combatants. Hezbollah is a terrorist organization, not a military unit beholden to the accepted conventions of war. Additionally, it was not Israeli soldiers who pulled off this op. It was clearly covert operatives. Given you know nothing of who or how they managed this, your uninformed criticism is...uninformed.
So, you're saying we can expect to see the same justification in the United States? As long as they're covert, justify their own targets, and ignore innocent civilians?
Because that's where such devaluation of innocent life is going.
