Europe wasn't breaking sovereign immunity / sovereign bank seizures when historically fighting each other, current actions historically unprecedented. So the answer is war is not sufficient excuse for RoW. EU extra delulu because RU/UKR not even over direct EU/NATO territory i.e. EU breaking sovereign immunity over "peripheral" interests. Like EU seize/sanction US when? Point of sovereign immunity is provide some semblance of neutrality for rest of world to do their thing while drunks fight, neutrals still want to buy from the drunks, EU has made things both hard not neutral.
