What other state:

-hoarded their resources while their neighbors suffered

-had a wall built at the border

-used resources hard to find elsewhere to create weapons

-has no semblance of democracy

-portrayed themselves as the good guys, saving the rest of the world from the horrible woes of the West

Wakanda is the Soviet Union confirmed. (possibly China and North Korea as well)
