Guerra do Vietnã (1955-1975): a atividade de inteligência e sua importância na Ofensiva do Tet

Abstract

This dissertation aims to examine the extent to which North Vietnam's intelligence activity influenced the strategic success of the Tet Offensive, which took place between January and February 1968, in the context of the Vietnam War. The research is based on a qualitative approach, based on the confrontation between theory and reality, with the aim of understanding how the intelligence invested in a state that was militarily inferior in conventional terms was able to produce relevant effects in the face of the material and technological superiority of the United States. The research analyzes how the North Vietnamese ability to produce and protect knowledge contributed to the success of the Tet Offensive, even though the operation culminated in a tactical defeat on the battlefield. The methodology adopted is based on the confrontation between theory and reality, allowing us to verify how the principles of intelligence activity were applied in practice. Throughout the work, the following are examined: the principles, fundamental concepts and historical evolution of intelligence activity; the historical context of the Tet Offensive and the factors that made its outbreak possible; the success of North Vietnamese intelligence in contrast to the failures of the American apparatus; risk analysis and its influence on offensive planning; and, finally, the results of the conflict interpreted in light of contemporary intelligence theory, with an emphasis on how intelligence activity contributed to the conduct of operations and influenced the strategic developments of the intervention. The relevance of this study lies in demonstrating that, in irregular and protracted conflicts, the state that structures a more agile and efficient intelligence cycle can conduct conflict actions in a more coordinated manner, gaining an advantage over its opponent. The Tet Offensive demonstrated that strategic surprise results not only from adversary failures, but from the deliberate ability of those who dominate the production and protection of knowledge, contributing to the decision-making process more effectively and timely.
