Protecting American interests in strategic materials such as oil, rubber, copper and zinc, was, according to the reasonable account of John Mason Hart, the Wilson administration's reasoning for invasion of Veracurz. The administration sought to bring about a beneficial stability through a policy of regime change.
However, it wasn't the regime of Victoriano Huerta, targeted for change, that was actual problem for the American holders of Mexican properties, but rather, the expropriations of Pancho Villa. Texas and Wall Street interests were growing worried as Villa's influence grew in the vicinity of Tampico. The objective of the Wilson policy was not so much the overthrow of Huerta, but to insure that Venustiano Carranza came out on top.
