Fear of Soviet Influence
America worried about growing Soviet power in Southeast Asia. The USSR provided North Vietnam with missiles, artillery, and economic aid throughout the conflict. American intelligence tracked Soviet ships delivering weapons to Vietnamese ports. U.S. officials saw each communist advance as a win for Moscow in the global Cold War chess match. This perspective transformed a civil war into a superpower confrontation with much higher stakes. American leaders believed showing resolve in Vietnam would discourage Soviet aggression elsewhere.
