U.S.–Mexico Relations: 4 Historical Episodes That Damaged Trust

Several U.S. actions in Mexico have left a legacy of resentment:

1. Mexican–American War (1846–48) – U.S. annexed Texas, invaded, and forced Treaty of Guadalupe Hidalgo, ceding half of Mexico’s territory.
2. U.S. Intervention in Mexican Revolution (1914–17) – Occupied Veracruz, backed Constitutionalists; seen as violation of sovereignty.
3. Bracero Program (1942–64) – Guest‑worker scheme criticized for exploitation and discrimination against Mexican laborers.
4. Operation Intercept (1969) – Unilateral border crackdown causing massive delays; viewed as heavy‑handed and disrespectful.

These episodes fostered enduring anti‑American sentiment and complicate bilateral relations today.
