Mandatory military service breeds corruption and violence, there’s a reason many countries abolished it. You are putting hundreds of dumbass teenage boys, whose parents weren’t rich enough to afford a waiver, all together governed by people who intentionally went into service (often not the brightest kind to say the least) and expect good things to happen. Countries that have immediate concern for invasions from neighbours should invest in an actual paid standing army, if they can’t - too fucking bad.
