I hope that as well, but I think neither the US, Israel nor China will stand idle next to a nuclear power getting dragged in front of the ICC - not with the numerous counts of crimes each of these countries could reasonably be charged with. The Israelis may be the only ones being able to get away with a lot of their stuff given that their opponents continuously enact crimes as well (e.g. hiding military command structures under hospitals and schools), but the US and China? They can't pull that card.
To be fair, the point of the ruse (in real wars; in heroic fiction this sometimes varies) is usually to get people killed, too; the question is just which people get killed.
This one infamous sword fight has now poisoned the well with respect to the global norm. Next time there's some other totally unaffiliated hat-wearing super-powered bandit who's stealing the Ark of the Covenant or the royal diamond or something, if THAT bandit tries to surrender, there's a high chance that person might be killed, because their surrender is distrusted since DragonWriter changed the norm and now every fight between supers and cops is now on "shoot to kill, no prisoners, take no quarter" stakes. Imagine how many times a famous super like Batman would have been killed if the authorities never accept a surrender because the surrender norm is ruined. It can be repaired but that might take a decade or more to repair the trust that was broken.
With strong norms about surrender, red cross medics being protected, etc., we can have things like the miracle of the WW1 Christmas Truce which help the war to be a little bit little less of pure hell, for all the pure-hearted or indifferent people dragged into being a soldier, perhaps even drafted or press-ganged, to be the disposable cannon fodder for a bloody and disease and gas drenched war for no good reason more than rich politicians' egos.

These people just want to go back home to their wife or their mum and would gladly gladly surrender if given the chance, but that's not possible if someone ruins the norm! It's like, for example even if someone is a super-villain for example, they should really not take human lives of innocent people, or destroy irreplaceable cultural heritage sites, or damage/burn an ecological area like a rain forest, because those, once lost, are forever gone, and leave our world impoverished.
