Final answer:
The U.S. should enter the war based on Wilson’s reasons of promoting democracy and peace through the League of Nations and adhering to his Fourteen Points, aligning with America's role as a moral leader.
Step-by-step explanation:
The United States should indeed enter the war for the reasons stated by Wilson, primarily to shape a new international climate and to support the growth of democracy worldwide. Our involvement is justified not by a desire for territorial gain or economic benefit but by the moral imperative to foster peace and democratic values through the establishment of the League of Nations and adherence to Wilson's Fourteen Points. This would honor Wilson's vision of America as a moral compass and advocate for a just and lasting global peace.
