You can't look only at track record. Afaik they have an unreasonable amount of infantry for purely defensive purposes. They're #3 globally in terms of firepower, of course they won't create trouble until they're reasonably sure they'll come out ahead. Once they're more powerful economically and militarily you'll have a an unscrupulous nation, with a dictator for life, capable of very long-term planning, leading a pretty explicitly racist people in need of massive amounts of natural resources.
So yeah, even though they're not currently adventurous militarily, I wouldn't count on that being the case forever.
