I think when you're having a proper war, 'total war' i.e. you're fighting to prevent your nation being destroyed then there is no law. Law can only exist in a meaningful way if a body has the means to enforce it, otherwise it's just a voluntary code and when fighting for survival it's not surprising those nicety's will go out of the window.
At the end of the day, no international body can do anything to stop a developed, well armed nation in a state of total war invading another nation, short of physically getting in it's way and destroying it's army. A pretty big ask from another nation who isn't involved in the conflict.
The wars we have these days are not real wars, they are just little spats where we basically bomb some massively less advanced nations a bit until we judge we've spent enough money on it.
The numbers lost (in terms of population percentage) are tiny (for us) and they are often fought at arms length so we can afford to abide by our own little let of rules and be all caring as we make sure to only kill 100's of people with bullets rather than gas because that's not allowed.
But if Britain was under a full scale land invasion from a nation with an army to match our own then any concept of the 'rules of war' would go out of the window pretty quickly when the survival of our nation was at risk. I think it would simply be a matter of kill them all at any cost.
As for things like systematic rape etc, the only reason I don't think we'd resort to that even in a total war situation is simply because it would be of minimum use to our aim, why bother sending in a load of men to kill and rape the population of a village in order to scare the locals into submission when you have the ability to wipe them off the map at the press of a button. After you've left a few villages as nothing but a smoldering mark on the earth, the rest would fall into line pretty quickly.
