You don't force people in the hopes they "find" their courage. Circumstances can force them, but people forcing others, no.
Your last point makes no sense. Any society that needs to force men to fight for it, is a society that deserves to die. If it were worthwhile, there would be no need to force them, in the face of an existential threat.
That's why it would only work with an existential threat. Even most armies tend not to do that.
Pick one.
If you need to force the men under the 'existential threat', that society should die.
But that was my point... By definition it is the former and not the latter.
Ehhhh... I don't think so. Some people's courage fails. That doesn't mean that society should die because of it.
That's like saying an army should never retreat, it should just fight and die if it has to give ground. That's unreasonable.
