Quoting the essay:

> Now, I want to leave aside, for the purpose of this essay, the use of lethal chemical agents in genocide, the use of non-lethal chemical agents entirely, as well as the use of things like defoliants that were not intended to cause casualties (even if they did). Those things are all important, but if we get into talking about them, we will never get anywhere. Instead, we’re focusing on the battlefield use of lethal chemical agents against either opposing combatants or civilian populations.
