Certainly making enlistment harder will decrease the number of troops (absent a draft) which has a non-zero probability of decreasing military adventurism, yes?
Discouraging a single enlistment seems to me like it has the same order-of-magnitude impact as casting a single vote.

How does making enlistment easier increase the percentage of volunteers that are good people?

Do you think more recruits means a "better" military?
