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.

There were various aspects of Sun Tzu's approach that appealed to Ho Chi Minh: a) to learn to understand both the enemy and yourself, to seek out his weaknesses and your own strengths, and act accordingly, b) to make ample use of subterfuge and stratagem in order to defeat or disarm your adversary, and c) to use outright violence only when absolutely necessary in the belief that political struggle was more effective than military 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.

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.

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.

Finally, in 1954 [Ho Chi Minh] agreed to the Geneva Agreement, which divided the country temporarily into two zones, in the hope that national elections might unify the country under his leadership.

Today [ Sun Tzu] ideas are not widely applied, at least among Islamic dissidents, whose profligate use of indiscriminate terrorism appears to limit the appeal of their ideas rather than to "win hearts and minds," as the Vietminh and the National Liberation Front did in Vietnam so many decades ago.
