10. Korea, Republic
- Military expenditure (2017): $39.2 billion
- Military expenditure as a % of general government expenditure (2017): 12.1% (#16 among countries)
- Military expenditure per capita (2017): $761 (#13 among countries)
Tensions between South Korea and its northern neighbor shaped much of the Republic's defense policy—and budget since the Korean Peninsula was divided at the end of the Korean War. A significant portion of the budget proposed in 2018 has been earmarked for efforts to increase cooperation between the two countries. President Moon Jae-in and North Korea's Kim Jong Un signed the Panmunjom Declaration after a summit in April last year and committed to halt in hostilities and denuclearization, though that goal remains elusive.

42. Denmark

- Military expenditure (2017): $3.8 billion
- Military expenditure as a % of general government expenditure (2017): 2.2% (#121 among countries)
- Military expenditure per capita (2017): $658 (#15 among countries)
Denmark has plans to increase its military spending to $229.7 million by 2023—a clear sign of its support for NATO as the Trump Administration continues pushing for more equitable contributions from countries in the alliance. A relatively safe country, most of Denmark's increase budget is aimed at improving cybersecurity to counter terrorist threats and possible aggression by Russia.
