Which government branch can declare war on another country?

congress

The Constitution of the United States divides the war powers of the federal government between the Executive and Legislative branches: the President is the Commander in Chief of the armed forces (Article II, section 2), while Congress has the power to make declarations of war.

hello!

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".

hope this
