Switzerland does have a mandatory service for all men, and doesn't have belligerent neighbours... But the Swiss army is still very much stuck in the cold war mindset of being afraid of an invasion. Last time there was a vote, the people refused to abolish the militia system.

Tbh I don't think military service is a problem as long as it's only used for defence and is properly setup, instead of have nutjobs running the small professional army and wanting war because they trained their whole life for it...
