The Wikipedia page states that Nigeria was supported by the USA, UK, AND USSR and that the Biafra Separatists were supported by France, China, and West Germany. Why did both sides have a mix of support between 1st and 2nd world countries when most conflicts of the era fell under a clear communist vs. capitalist division?
