Vietnam 1945-1963
Long before the US military got involved there directly, Vietnam was the CIA's war. At first they waged it on behalf of the French, who struggled for nine years, from 1945 to 1954, to recapture their one-time colony (despite the war's unpopularity with the French public).
Even with CIA mercenaries fighting alongside the French, and air support from the CIA's Air America (at the time, the largest "private" airline in the world), the effort proved tobe in vain.
The 1954 Geneva Accords temporarily divided Vietnam in preparation for elections in 1956. But the US wasn't interested in elections.
In the North, CIA "psywar" expert Ed Lansdale spread the rumor that the US was planning to nuke the area. This, along with other, similar tactics, created an exodus of over one million refugees, who were ferried to the south by CIA ships and planes.
In the South, the CIA wrote a constitution for "South Vietnam" (which had never been considered a separate country before), installed Ngo Dinh Diem and gave him the job of crushing anyone who had opposed the French.
US support for Diem was based on the belief that he was the one politician in Vietnam who would never negotiate with Ho Chi Minh. When, after nine more years of futile warfare, even Diem found such negotiations desirable, he was tossed aside as casually as he'd been put in place. In November 1963, he was deposed in a CIA-sponsored coup, then assassinated.
In 1945, one US intelligence agent had described Ho Chi Minh as the "strongest and perhaps the ablest figure in Indochina, and...any suggested solution which excludes him is...of uncertain outcome." Unfortunately, such insights were ignored in Washington as the Cold War solidified.
Vietnam 1964 - 1975
Following the deaths of JFK and Ngo Dinh Diem, it was only a matter of time before US combat troops became involved in Vietnam. Within days of the JFK assassination in November 1963, President Johnson had reversed JFK's plan to withdraw US personnel by the end of 1965. As LBJ told one impatient general, "Just get me elected; you can have your damn war."
In August 1964, the CIA and related military intelligence agencies helped fabricate a phony Vietnamese attack in the Gulf of Tonkin off North Vietnam. This supposed act of North Vietnamese aggression was used as the basis for escalating US involvement.
In March 1965, US troops began pouring into Vietnam. Nine years of backing the French, another nine years of backing Diem and two more years of CIA operations had failed. From this point on, the US Army took over the war effort.
Since the Vietnamese people overwhelmingly supported their own National Liberation Front (the NLF, or "Viet Cong" as we called it), the Army began destroying villages, herding people into internment camps, weeding out the leaders and turning the countryside into a "free-fire zone" (in other words, shoot anything that moves).
The CIA still had a role to play, however. Called Operation Phoenix, it was an assassination program plain and simple. The idea was to cripple the NLF by killing influential people like mayors, teachers, doctors, tax collectors-anyone who aided the functioning of the NLF's parallel government in the South.
Many of the "suspects" were tortured and some were tossed from helicopters during interrogation. William Colby, the CIA official in charge of Phoenix (he later became director of the CIA), insisted this was all part of "military necessity"- though he admitted to Congress that he really had no idea how many of the 20,000 killed were Viet Cong and how many were "loyal" Vietnamese.
Colby's confusion was understandable, since Phoenix was a joint operation between the US and the South Vietnamese, who used it as a means of extortion, a protection racket and a way to settle vendettas. Significantly, the South Vietnamese estimated the Operation Phoenix death toll at closer to 40,000. Whatever the exact number, there's no question the killings were necessary-after all, we were trying to prevent a blood bath.
