Your claim about fluorine being essential for organophosphate nerve agents is incorrect. The original nerve agent, tabun, contains no fluorine at all for example. Neither do VX, parathion, or paraoxon.

Sarin does, and the article is talking about sarin. Either way I’m sure you’d agree that isopropanol isn’t a precursor to sarin, yes? You’d also probably admit that you’re not getting methylphosphonyldifluoride from fucking toothpaste. Lecture about the mechanisms of organophosphates on AChE aside.
