1. A War of National Reunification Misread as a Proxy Conflict
American policymakers consistently framed Vietnam through the lens of Cold War containment, treating the conflict primarily as Soviet and Chinese expansionism wearing a local disguise. The Vietnamese communist movement, however, drew on deep nationalist traditions and a decades-long resistance to French colonial rule. Ho Chi Minh and his successors were committed Marxist-Leninists, but they were equally committed nationalists, and that combination gave the insurgency a motivational depth and popular resonance that outside support alone could never have supplied. Treating the war as a domino in a geopolitical game meant misunderstanding what the other side was actually fighting for.
Why it matters: This misreading shaped every strategic decision that followed. When the enemy's core motivation is not ideology but national self-determination, military pressure tends to strengthen rather than break popular resolve.
