Omg you said WTHeck!!!!!! I am guessing they just want us to fail in the future...but we are totally gonna need to find x and y in the future!! lol :)
Im not sure if this is correct but here i go
1. Eastern Europe (Poland, Czechoslovakia etc.)
2. North Korea (They ere liberated by the Soviets during WW2 from the Japanese)
3. East Germany and East Berlin (They were split up after WW2)
4. They also occupated parts of Japan to help them rebuild
