Ford, Carter and Cambodia: US foreign policy and the Khmer Rouge

This thesis is an investigation into the US response to the Khmer Rouge regime in Cambodia between 1974 and 1981. It argues that the US experience in the Vietnam War acted as a causal factor in the formulation of its Cambodian policy during the presidencies of Gerald Ford and Jimmy Carter. From taking power in April 1975 to their removal by the Vietnamese in January 1979, the Khmer Rouge initiated a revolution unrivalled in the 20th Century for its brutality and for the total eradication of modern society. This thesis demonstrates that the Ford administration viewed Cambodia only as it pertained to their strategy in Vietnam and, following US disengagement from Indochina all but ignored the atrocities occurring there as they instead pursued informal relations with the Khmer Rouge as a means of punishing the Vietnamese. The Carter administration formulated a foreign policy based on human rights yet failed to adequately address the genocide that occurred in Cambodia due to its temporal and regional proximity to Vietnam. Instead, this collective reluctance to reengage with the region and the resulting anti-Vietnamese attitude reinforced Brzezinski’s broader global strategy that allied the US with China in support of an independent Cambodia to further isolate Hanoi. Thus this thesis argues that the distorting impact of the Vietnam War, as well as global Cold War calculations, undermined any appreciation of the Cambodian conflict and caused both administrations to pursue policies in Cambodia that ultimately supported the Khmer Rouge regime. This project incorporates declassified material from the Ford and Carter Presidential Libraries, supplemented by the material from the National Archives and Library of Congress, and relevant newspapers and periodicals. It demonstrates that the limitations placed upon US foreign policy by their experience in the Vietnam War may be used to reveal unexplored elements in US-Cambodian relations.

Plasmid biology of natural Lactococcus lactis strains and molecular mechanisms of bacteriophage-host interaction

Lacticin 3147, enterocin AS-48, lacticin 481, variacin, and sakacin P are bacteriocins offering promising perspectives in terms of preservation and shelf-life extension of food products and should find commercial application in the near future. The studies detailing their characterization and bio-preservative applications are reviewed. Transcriptomic analyses showed a cell wall-targeted response of Lactococcus lactis IL1403 during the early stages of infection with the lytic bacteriophage c2, which is probably orchestrated by a number of membrane stress proteins and involves D-alanylation of membrane lipoteichoic acids, restoration of the physiological proton motive force disrupted following bacteriophage infection, and energy conservation. Sequencing of the eight plasmids of L. lactis subsp. cremoris DPC3758 from raw milk cheese revealed three anti-phage restriction/modification (R/M) systems, immunity/resistance to nisin, lacticin 481, cadmium and copper, and six conjugative/mobilization regions. A food-grade derivative strain with enhanced bacteriophage resistance was generated via stacking of R/M plasmids. Sequencing and functional analysis of the four plasmids of L. lactis subsp. lactis biovar. diacetylactis DPC3901 from raw milk cheese revealed genes novel to Lactococcus and typical of bacteria associated with plants, in addition to genes associated with plant-derived lactococcal strains. The functionality of a novel high-affinity regulated system for cobalt uptake was demonstrated. The bacteriophage resistant and bacteriocin-producing plasmid pMRC01 places a metabolic burden on lactococcal hosts resulting in lowered growth rates and increased cell permeability and autolysis. The magnitude of these effects is strain dependent but not related to bacteriocin production. Starters’ acidification capacity is not significantly affected. Transcriptomic analyses showed that pMRC01 abortive infection (Abi) system is probably subjected to a complex regulatory control by Rgg-like ORF51 and CopG-like ORF58 proteins. These regulators are suggested to modulate the activity of the putative Abi effectors ORF50 and ORF49 exhibiting topology and functional similarities to the Rex system aborting bacteriophage λ lytic growth.

The Ford administration, Angola and the perception of Post-Vietnam US credibility, 1974-1976

This thesis is a study of how the Gerald Ford administration struggled to address a perceived loss of US credibility after the collapse of Vietnam, with a focus on the role of Secretary of State Henry Kissinger in the formulation, implementation and subsequent defence of US Angolan policy. By examining the immediate post-Vietnam period, this thesis shows that Vietnam had a significant impact on Kissinger’s actions on Angola, which resulted in an ill conceived covert operation in another third world conflict. In 1974, Africa was a neglected region in Cold War US foreign policy, yet the effects of the Portuguese revolution led to a rapid decolonization of its African territories, of which Angola was to become the focus of superpower competition. After South Vietnam collapsed in April 1975, Kissinger became fixated on restoring the perceived loss of US prestige, Angola provided the first opportunity to address this. Despite objections from his advisors, Kissinger methodically engineered a covert program to assist two anti-Marxist guerrilla groups in Angola. As the crisis escalated, the media discovered the operation and the Congress decided to cease all funding. A period of heated tensions ensued, resulting in Kissinger creating a new African policy to outmanoeuvre his critics publicly, while privately castigating them to foreign leaders. This thesis argues that Kissinger’s dismissal of internal dissent and opposition from the Congress was influenced by what he perceived as bureaucrats being affected by the Vietnam syndrome, and his obsession with restoring US credibility. By looking at the private and public records – as expressed in government meetings and official reports, US newspaper and television coverage and diplomatic cables – this thesis addresses the question of how the lessons of Vietnam failed to influence Kissinger’s actions in Angola, but the lessons of Angola were heavily influential in the construction of a new US-African policy.
