Introduction
A century of courtship, war, and pressure
Americans tend to remember Vietnam as a war that ended in 1975. For the Communist Party of Vietnam, the contest with the United States was always fought on two fronts: on the battlefield, and in American politics and opinion. That second front did not close when Saigon fell.
Our argument is that Hanoi's influence in America has run on two tracks. The first is persuasion and propaganda: Hồ Chí Minh's letters to Washington and his borrowed Declaration of Independence, guided tours of bomb damage for activists, clergy and editors, Radio Hanoi, staged POW "confessions" and releases timed to visiting delegations. The second is operational: agents planted in Saigon's army, palace and press corps, including Time magazine's own correspondent; a USIA officer and a courier who passed diplomatic cables to Hanoi's diplomats and were convicted in 1978; torture of American prisoners; and, since the war, hacking, spyware, and the surveillance and abduction of critics abroad.
Opinion and fact are kept separate. Every entry gives the documented record with linked sources and a status label. Our interpretation appears only in clearly marked Our Take boxes. Being critical of the Party also means being careful: Hanoi's own hero stories inflate its spies, Cold War accusations were not always true, and opposing the war was not the same as serving Hanoi. Vietnamese Americans, most of whom fled communism, are not the regime; they have been among its main targets. Criminal cases involving Vietnamese Americans that have nothing to do with Hanoi are not included. The Named Spies theme lists every publicly documented Hanoi agent, officer, courier, propagandist and defector we could find, plus the related procurement, hacking and abduction cases, with each case's outcome.

The Second Front
From a petition at Versailles in 1919 to registered lobbyists in 2025: how Vietnam's Communist Party has worked to win over, divide, watch and silence Americans.

How this guide was built
Entries were researched in October 2026 from primary government documents (Justice Department and FBI releases, court opinions and dockets, FARA filings, the State Department's Office of the Historian and Foreign Relations of the United States, CIA reading-room releases, congressional hearings and the National Archives), Vietnamese Party and state documents where available, the Wilson Center's Cold War International History Project, contemporary reporting (AP, Reuters, BBC, CNN, NBC, The New York Times, Los Angeles Times, RFA, VOA), rights groups such as Amnesty International and Human Rights Watch, and Wikipedia overview articles that cite them. Source links were checked at the time of writing; a few major news sites block automated checks and were confirmed by search.
Quotations appear only where the wording was found in a primary or cited source. Elsewhere the guide paraphrases. Several widely repeated quotations and claims that could not be traced to a reliable source were left out.
Point of view. This guide has an editorial position: it is critical of the Communist Party of Vietnam. That position appears only in boxes labeled Our Take and in the central essay. The sections labeled The Record contain only sourced statements of fact. Where U.S. policy failed, from ignoring Hồ's letters to the Gulf of Tonkin, the guide says so.
Fairness. A conviction in a one-party state's courts is not the same as one in an independent court, and Hanoi's official hero biographies are labeled as its own account. Antiwar Americans are not described as agents unless a court or credible evidence says so; Operation CHAOS found no foreign control of the movement. A decision not to charge is not proof of innocence. Rumors of "communist agents" have also been used to smear people within the Vietnamese-American community, so unsupported accusations against named people are not repeated.
Limits. Much of Hanoi's intelligence work is known only from its own publications, defectors, or classified files. There has been no public U.S. espionage prosecution for Vietnam since 1978. The Named Spies audit covers people convicted, charged, officially identified, or self-identified, plus officers and defectors named in reliable sources.
