This is significant because historically the most common way for men to avoid conscription was to emigrate for school/work and just not come back until they'd acquired dual citizenship (which usually* exempts you from conscription). A nice side effect of this is a pretty significant brain drain, when your people are motivated to leave because they want to avoid 1-3 years of military service for basically no pay (3 if you're selected to serve as an officer, so Doctors, Engineers, and I believe certain other specializations, 1 otherwise). It's funny (and depressing) to think about how were it not for some luck and some hard work, I'd probably be in my first of 3 years of conscription right this second. Instead I'm on HN :) * Subject to the feelings and competence of the bureaucrats processing the paperwork, as well as any presidential decrees which might interfere with this policy.
