What was the main outcome of Villa's attacks on U.S. territory?

The main outcome of Villa's attacks on U.S. territory was that it prompted a military response from the U.S. government. In 1916, Pancho Villa led a raid on Columbus, New Mexico, which resulted in the death of several Americans. This attack alarmed the U.S. government and prompted President Woodrow Wilson to respond by sending General John J. Pershing and a military expedition into Mexico in pursuit of Villa. The expedition marked a significant moment in U.S.-Mexico relations and showcased the U.S. government's willingness to intervene militarily in its neighbor's affairs due to security concerns.

Other outcomes, such as increased support for Villa among Mexicans or a peace treaty between the two nations, did not materialize directly from these attacks. Instead, the raid intensified tensions and distrust, indicating that the immediate military response overshadowed any potential for diplomatic solutions or increased domestic support for Villa in Mexico.
