Well it seems like you think you know these people you claim you don’t know. For instance, you keep accusing them of being fearful, and that being the only reason you can think of why people would not be willing to go to war.
Can you think of no other reason why people would be unsuited for the military and combat? Because I assure you, boot camp weeds out people who volunteer, and that the military finds unsuitable. Do you think cowardice is the only thing they look for?
