Which country did North Korea invade in June 1950?

all together there were 21 countries from the United nations involved in the Korean war . Britain suffered some 1100 kia . The answer omits this and gives the impression that only the USA were there.

Pah, Non-South Korean troops were overwhelming from the USA with over 300.000 compared to about 50.000 others.
