Before the civil war, who did the south think would assist them?

Before the Civil War, the South thought that France and Great Britain would assist them.

Explanation:

Before the Civil War, the southern states believed that they would be supported by the main European powers: France and Great Britain.

This was due to two main factors: on the one hand, Southerners believed that the European textile industry was largely dependent on American cotton production; In addition, they believed that the European powers would seek to limit the power of the United States, which, starting with the Monroe Doctrine, had limited European expansionism in the Americas.

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".
