Earlier this year, US intelligence discovered that the Russian government planned to assassinate the chief executive of a powerful German arms manufacturer which has been producing artillery shells and military vehicles for Ukraine, according to five US and western officials familiar with the episode.
The difference is that the receptionist isn’t being targeted, the factory is. I think that holds true for the CEO also. If they’re collateral damage it isn’t a warcrime, if they’re specifically targeted it is.
Fair enough, though there are some employees whose death would meaningfully impact arms production, like a star engineer or a tech with hard to replace skills. A CEO’s death would also likely meaningfully impact arms production.
And frankly, I think anyone directly involved in making weapons that are killing your people is fair game. The army also has receptionists who don’t participate in combat operations, but they know what they’re involved in.
