In the most general sense, President Wilson decided in favor of American entry into the First World War for which of the following reasons?

A) The German-Mexican alliance threatened the security of the United States.
B) American munitions manufacturers pushed him in that direction.
C) He wanted a peace fashioned in accordance with Wilsonian, and thus American, ideals.
D) He wanted to acquire a colonial empire for the United States.

Wilson believed that American entry was necessary to ensure that the outcome of the war would align with his vision for a world order based on democratic values and international cooperation. This is evident in his famous "Fourteen Points" speech, which outlined his goals for the post-war world. The German-Mexican alliance and the influence of munitions manufacturers may have played a role in the build-up to American entry, but Wilson's broader vision for a new world order was the primary motivation for his decision. Option D can be ruled out as Wilson was opposed to the idea of colonialism.
