I decided that after returning to the US to pursue an academic career I would eventually study the life of Ho Chi Minh to find the secret of his success.

What is the influence of Sun Tzu in the world today? Perhaps there are others who are better qualified than I to speculate about that question. Sun Tzu's ideas, as expressed in his famous treatise, have undoubtedly influenced the nature of many revolutionary movements that are arrayed against more powerful forces, and in some cases - as in Vietnam - have played a useful role in bringing about success. But such ideas are always in conflict with other deepseated emotional factors, which propel dissident movements into the rampant use of terrorism and other forms of anarchistic struggle.

The influence of Sun Tzu on other North Vietnamese military strategists is harder to answer. Certainly many of the key leaders in Hanoi were aware of Sun Tzu and made use of his ideas - Vo Nguyen Giap applied many of these ideas in seeking out weak elements in the enemy's defenses, as did Truong Chinh, whose famous treatise, The Resistance Will Win (1947), cited the ideas of Mao Zedong as a model for the North Vietnamese to follow.

Many of the ideas of Sun Tzu and Mao Zedong came naturally to the young Ho Chi Minh, who would probably have applied the same strategy even had he not been aware of them.

From the outset, when [Ho Chi Minh] became a member of the French Communist Party in 1920, he was an independent thinker who adjusted Marxist-Leninist ideas and tactics to what he perceived to be the concrete situation in Indochina.

When he served in China during World War II, [Ho Chi Minh] learned about Mao Zedong's tactics of guerrilla war against the Japanese (and later against Chiang Kai-shek's forces), and he translated some of Mao's works into Vietnamese. But it is clear that his own ideas on how to counter the enemy ran along the same lines.

In the end, many of his more militant colleagues began to feel that [Ho Chi Minh's] tendency to compromise, and his reluctance to confront the enemy directly, was a sign of weakness. The decision to confront the United States in 1963-1965 was a tacit recognition that Ho's approach had failed.
