미국 • (Miguk) (hanja 美國, 米國)^{[note 1]}

↑ ^1.0 ^1.1 米國 was used during the Japanese colonial period, presumably from Japanese 米国. After WWII, South Korea reverted to 美國 (literally “beautiful country”), while North Korea continues to use 米國 (literally “rice country”), perhaps reflecting differing political attitudes towards the USA.
