Are War Crimes Ever Justified? The laws haven't been made in a vacuum without knowledge of actual warfare. If you know the laws, it should be evident that it doesn't limit the way to destroy the enemy combatants. — ssu
We're dealing with a hypothetical here posed by
@RogueAI. Nor do rules created in the 1920s always maintain the same character that they did as years go on. These rules were created in the 20s, so I ask: Was it ok to use in WWI? I'll readily admit that gas is a nasty weapon and not something that I would use on the battlefield unless extraordinary circumstances. But I would say this qualifies as one.
In this scenario your country's (UK) beachfront is being stormed by Nazis. Intel says gas would be extremely effective - perhaps because they're not wearing gas protection or perhaps because a new type of gas has been synthesized.
There's also conventional means of resistance but we're not given much info as to Britain's capability here and we could envision a wide number of scenarios from futile to easily being able to ward them off. Obviously the more futile potential resistance is the greater the attraction is towards using gas. But the UK has lost air superiority here.
In broad strokes though, if a large Nazi invading force combined with air superiority landed on the British beachfront in '43 or '44 and I (the Prime minister) learned that gas would be extremely effective and I used it and
it did prove extremely effective would I feel vindicated? Yes. My first responsibility is to my people and my country is in imminent danger. Not my first choice of weapon, but if my hand is forced I'll use it.
If the invading force was small I would not use it though. I am only talking a very large, very serious invading force that would surely successfully invade otherwise.
