I would point out the humour in an emotional reaction to my choice of words derailing the conversation but the realisation that there are people who believe their "great military leaders" are somehow "above" emotions and that this is a good thing is genuinely terrifying
People including myself have emotional reactions, but I choose to respond with a reasoned explanation, and I certainly wouldn't engage in violence with you over it, even if a portion of my lizard brain demanded that I should.
You've added the words "primary driver" here yourself, I never made such a claim. But I hope you can see that not only that leap but also your desire to overcome your "animalistic" emotions are both rooted in emotion.
I won't waste my time looking for evidence for a claim I didn't make and I don't think it's up for debate that the majority of people in the armed forces are "armed and emotional." But in terms of the original claim that checks and balances only serve up to the point of human failure I could point to any number of examples and would repeat the fact that others have raised some in this thread.
> it comes down to people who are armed and emotional.
This implies that real people are making emotional decisions instead of guided by reason.
> technical terms like this of what is and isn't permitted
These technical terms that you are discounting are some of the real weapons that human beings use to give them options beyond simply following orders that they disagree with.
This is an incredibly nuanced topic, and to reduce it to people making "armed and emotional" decisions shows a lack of appreciation for what people try to do in difficult situations.
