This is likely based loosely on something I posted a few days ago, where I said I hold the unpopular opinion that it’s usually unethical to join the military. Not immoral, unethical. I’m hesitant to elaborate, but often choose unwisely, so I’ll elaborate a bit.
First, I say “unethical” because, while I don’t claim to have any supernatural insight into ethics, I do ascribe the view that ethics are as subjective as mathematics, that there are certain principles that apply better to the actual world we live in than others. I may poorly understand those principles, but it seems to me that they’re probably a feature of the universe, and it’s a good idea to try to understand them.
Second, I figure that we should try to act on the ethical principles to the best of our understanding. And even if I may respect your different ethical position, I may still think it’s wrong, and act to prevent you (or dissuade you) from engaging in acts I understand to be unethical.
Third, armed forces require you to subordinate your understanding of ethics to someone else’s. This may mean killing people even when you do not believe the situation warrants it.
In extreme cases, e.g., fighting Nazis when the Nazis look like they stand an extremely good chance of taking over much of the world, the ill of subordinating your ethical understanding to that of other people can be overwhelmed by the ethical necessity. The ends justify the means, sometimes.
But in general the people at the top of military chains of commands have not convinced me that they’re adequately concerned about protecting innocent lives. This applies to modern US military commands, as well as those of every other nation I’m familiar with. Including Canada’s.
So I don’t think it’s ethical to join the military.
Again, I recognize this is a vastly minority opinion. I don’t expect others to agree. I think others can disagree, and can even join the military, and still be good people who are worthy of respect. But I’ll not respect them for making this specific decision, and I’ll wish they’d chosen otherwise.
