took office, conservatives retook power through a coup led by Victoriano Huerta. Wilson rejected the legitimacy of Huerta's "government of butchers" and demanded Mexico hold democratic elections. After Huerta arrested U.S. Navy personnel who had accidentally landed in a restricted zone near the northern port town of Tampico, Wilson dispatched the Navy to occupy the Mexican city of Veracruz. A strong backlash against the American intervention among Mexicans of all political affiliations convinced Wilson to abandon his plans to expand the U.S. military intervention, but the intervention nonetheless helped convince Huerta to flee from the country. A group led by Venustiano Carranza established control over a significant proportion of Mexico, and Wilson recognized Carranza's government in October 1915. Carranza continued to face various opponents within Mexico, including Pancho Villa, whom Wilson had earlier described as "a sort of Robin Hood." In early 1916, Pancho Villa raided the village of Columbus, New Mexico, killing or wounding dozens of Americans and causing an enormous nationwide American demand for his punishment. Wilson ordered General John J. Pershing and 4,000 troops across the border to capture Villa. By April, Pershing's forces had broken up and dispersed Villa's bands, but Villa remained on the loose and Pershing continued his pursuit deep into Mexico. Carranza then pivoted against the Americans and accused them of a punitive invasion, leading to several incidents that nearly led to war. Tensions subsided after Mexico agreed to release several American prisoners, and bilateral negotiations began under the auspices of the Mexican-American Joint High Commission. Eager to withdraw from Mexico due to tensions in Europe, Wilson ordered Pershing to withdraw, and the last American soldiers left in February 1917. Neutrality in World War I World War I broke out in July 1914, pitting the Central Powers (Germany, Austria-Hungary, the Ottoman Empire, and later Bulgaria) against the Allied Powers (Britain, France, Russia, Serbia, and several other countries). The war fell into a long stalemate with very high casualties on the Western Front in France. Both sides rejected offers by Wilson and House to mediate an end the conflict. From 1914 until early 1917, Wilson's primary foreign policy objectives were to keep the United States out of the war in Europe and to broker a peace agreement. He insisted that all U.S. government actions be neutral, stating that Americans "must be impartial in thought as well as in action, must put a curb upon
