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.

39. Sudan

- Military expenditure (2017): $4.4 billion
- Military expenditure as a % of general government expenditure (2017): 30.9% (#1 among countries)
- Military expenditure per capita (2017): $108 (#40 among countries)
Sudan may have spent anywhere from 25 to 70% of its total budget on its military engagements around the world. The exploding costs are driven by Sudanese wars in Darfur, South Kordofan, and Blue Nile; economists estimate that Sudan spends millions of dollars a day on warfare. Corruption and low spending on health and education are a result, and some Sudanese residents believe that these internal conflicts might be more easily resolved if the government were to spend less money on fighting and more on helpful social services.
