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.

43. Portugal

- Military expenditure (2017): $3.8 billion
- Military expenditure as a % of general government expenditure (2017): 3.9% (#88 among countries)
- Military expenditure per capita (2017): $367 (#25 among countries)
Mere decades after the end of their brutal colonial regime in Africa, Portuguese forces have returned to the continent for “peace enforcing” missions in the Central African Republic and Mali. These forays into counter-terrorism operations mark Portugal's attempts to stabilize the region during its presidency of the European Union. Portugal is also close geographically to countries like Libya, leaving it more exposed to possible terrorist attacks.
