What is the connection between Pancho Villa and the United States' military preparedness during WWI?

The failure of the US army to complete it's true objective (to capture Pancho VIlla), as well as garner support from the locals, and the failure of being an effective fighting force, saw that the US military was extremely unprepared and needed a re-work. This was especially true and the restructure direly needed in the rising tide of World War I.

This was put partially in place by declaring peace in the early days which allowed for the production of military hardware, as well as the slow process of training new troops, which was further sped up with the US inclusion into the world war militarily.
