In Africa[edit]

Among African nations, Nigeria has shown the will to intervene in the affairs of other sub Saharan African countries since independence. It is said that one of the reasons Yakubu Gowon was removed from office had  been the squandering of Nigeria’s resources in such far-away lands as Grenada and Guyana, with no returns, economic or political for Nigeria. The philosophy of subsequent military governments in Nigeria was that in an increasingly interdependent world, a country cannot be an island.[14]
