The correct answer is A) A few strong nations held economic and political power in the global world.
The main idea of the passage is "A few strong nations held economic and political power in the global world."
After so many hostilities, the CIA espionage, and the failed invasion of Bay of Pigs in 1961, Cuban leader Fidel Castro delivered the Speech "Second Declaration of Havana” on February 4, 1962. In that speech, he referred to the political and economic dominion of powerful countries over most of the poor nations of the world. Fidel Castro sent the clear message that Cuba was going to resist the attacks of the imperialist nation, referring to the United States.
