Jonathan Haslam's Russia's Cold War is the latest effort by a western scholar to synthesize new research and findings on the Soviet role in the Cold War. Citing an array of published Russian archival material, Haslam seeks to resuscitate the traditional western Cold War view that the conflict was the inevitable result of communist expansionism. However, the material cited by Haslam does not support such a conclusion and he ignores conflicting evidence and views. The Cold War was a war of choice not necessity, the result of distorted perceptions and calculations by both sides, aided and abetted by generations of ideologically aligned historians.  相似文献

Some have suggested that Richard Nixon's narrow victory in the US presidential election of November 1968 was due to his persuading the Government of South Vietnam (GVN) to boycott the Paris peace talks for the settlement of the Vietnam War between the US government, that of the Democratic Republic of North Vietnam (DRV) and the representatives of the communist guerrilla movement in South Vietnam. This seems doubtful. The new president had abandoned the hawkish stance he had adopted when vice‐president in the Eisenhower administration and was anxious to bring the unpopular war to an end. The question was: how? The president, together with his influential National Security Advisor, Henry Kissinger, adopted a policy of ‘Vietnamization’, which involved the progressive scaling down of the US military presence and the handing over of responsibility for waging the war to the GVN. At the same time, the president recognized that too precipitate an American withdrawal and, above all, one which took place under the terms of an agreement which was too favourable to the communists, would have a deleterious effect upon its allies and its own position as a Great Power. In order to bring about a satisfactory agreement with the DRV, the US employed a twin strategy: secret talks between Kissinger and senior DRV representatives in Paris, coupled with veiled threats of an escalation of the war if the communists acted unreasonably and occasional displays of military strength, such as the incursion into Cambodia in 1970. Although it seemed, briefly, that there might be a breakthrough in Kissinger's secret negotiations with the DRV later in 1971, they broke down mainly as a result of the communists' insistence that the US in effect dismantle the South Vietnamese government for them. An angry Nixon secretly considered retaliation against the DRV to force it to modify its demands and publicly revealed the existence of the negotiations and much of their content to the American people in a speech on 25 January 1972. At the same time, however, he insisted that Vietnamization would continue.  相似文献

IThis second article on the Johnson administration's policy towards the war in Vietnam, based on published American documents, covers the period from July 1965 to March 1968. Although it is now clear that the Communist forces in Vietnam encountered considerable difficulties as a result of the steadily growing commitment of US ground forces, the Americans encountered difficulties of their own: notably the problem of persuading their South Vietnamese ally to implement what they regarded as the necessary political and military policies; and the increasing criticism of the war at home. The bombing of North Vietnam was a key issue for the administration. While the president's military advisers were continually pressing for further escalation, most of the civilians were sceptical. The latter felt that the bombing was not achieving its principal objective of reducing the flow of men and supplies from North Vietnam into South Vietnam, was unpopular at home and abroad and, if increased, posed serious risks of Chinese and Russian involvement. Although the bombing was temporarily halted or restricted more than once during this period in an attempt to facilitate a negotiated settlement, nothing was achieved. On 1 November 1967 Secretary of Defense Robert McNamara's growing disillusionment with the war prompted him to send a lengthy memorandum to President Johnson arguing for the cessation of the bombing of the North and the stabilization of the American effort in the South. Rejected at the time, this policy was partially implemented as a result of the Communist Tet offensive of February 1968, when countrywide attacks were beaten back after failing to trigger the expected popular uprising against the Americans and the South Vietnamese government, while at the same time producing a surge of hostility to the war in the United States. Three men‐McNamara's successor, Clark Clifford, Secretary of State Dean Rusk and White House aid Harry McPherson‐were largely responsible for persuading President Johnson to accept the fact that the war could not continue on the same basis as before and that de‐escalation was a better option. The president rejected the military's request for a huge increase in the number of US troops and, on 31 March 1968, announced a halt to the bombing north of the 20 th parallel and called for immediate peace talks. He also surprised the nation and his advisers by declaring that he would not run for the presidency in the election due in November 1968, preferring to concentrate on the search for peace during the remainder of his period in office.  相似文献

This article examines the reception of revivalism inspired by the work of Dwight Moody and Ira Sankey in the Wanganui‐Manawatu region of New Zealand in the 1870s and 1880s. The success of Moody and Sankey's 1873–75 British campaign inspired interest in revivalism, and led to rapid and widespread adoption of their distinctive methods. Though it aroused opposition in some quarters, Moody and Sankey style revivalism became established as a significant feature of New Zealand religiosity at that time. Some aspects continued to appeal well into the twentieth century. This article traces the rise and growth in influence of this form of revivalism, and considers reasons for its appeal in late nineteenth‐century New Zealand.  相似文献

Sydney's water crisis has been attributed to long-term drought, a population growing at >50 000 a year, the early impacts of global warming and the demands of a 4.2 million population leading a water-thirsty lifestyle. In this paper the drought is linked with a return to a drought-dominated flow regime in eastern New South Wales. This began in 1991 and is associated with a shift from flood to drought domination that occurs every 20 to 50 years. Its impacts will be further exaggerated by global warming. The reduction of runoff into Sydney's reservoirs is due primarily to regime shift, resulting in the diminution of inflows to about 25% of their levels in the 42 years before 1991. Possible ways of managing these dwindling water resources include building more reservoirs, exploiting largely unknown sources of groundwater, constructing a desalination plant, harvesting rainwater in the city, recycling used urban water and reducing individual water use. Despite arguments against the first three of these options, a desalination plant is currently under construction and investigations of deep groundwater proceed (shelved 18th June, 2008). Given that sources of water are distant and located in areas where rainfall reductions have been significant, greater efforts should be made to use water already in the city (rainfall and recycled water). Water restrictions and better domestic management of water are also areas where great savings can be and have been made.  相似文献

The primary focus of a structural shake table system is the accurate reproduction of acceleration records for testing. However, many systems deliver variable and less than optimal performance, particularly when reproducing large near-field seismic events that require extreme table performance. Improved identification and control methods are developed for large hydraulic servo-actuated shake table systems that can exhibit unacceptable tracking response for large, near-field seismic testing. The research is presented in the context of a 5-tonne shake table facility at the University of Canterbury that is of typical design. The system is identified using a frequency response approach that accounts for the actual magnitudes and frequencies of motion encountered in seismic testing. The models and methods developed are experimentally verified and the impact of different feedback variables such as acceleration, velocity and displacement are examined.

The methods show that shake table control in testing large near-field seismic events is often a trade off between accurate tracking and nonlinear velocity saturation of the hydraulic valves that can result in severe acceleration spikes. Control methods are developed to improve performance and include both acceleration and displacement feedback to reduce the acceleration spikes, and record modification, where the reference signal is modified to conform to the shake table's operational parameters. Results show record modification gives exact tracking for near-field ground motions, and optimal system response for reference signals with velocity components greater then the system capabilities. Overall, the research presents a methodology for simple effective identification, modelling, diagnosis and control of structural shake table systems that can be readily generalised and applied to any similar facility.  相似文献

The Cambridge history of the Cold War is a three‐volume work by 75 contributors, mostly from the United States and the United Kingdom, and is intended as ‘a substantial work of reference’ on the subject. The bulk of the text deals, in frequently overlapping chapters, with the main protagonists of the conflict—viz. the United States, the Soviet Union and the People's Republic of China—and the areas in which they clashed. At the same time, it aims to go ‘far beyond the narrow boundaries of diplomatic affairs’, although it is not always successful in doing so. In analysing the origins of the Cold War, the contributors pay perhaps too much attention to ideology as opposed to geopolitics, a flaw which is made easier by the absence of sufficient historical background. On the other hand, the duration of the conflict and the failure of various attempts at détente is more successfully explained in terms of the zero‐sum game nature of the conflict and its progressive extension from Europe across the rest of the world. When it comes to the end of the Cold War, the overall conclusion is that this came about through both a shift in the international balance of power following the Sino‐Soviet split and the political and economic problems of the Soviet bloc. It is generally agreed that Mikhail Gorbachev's willingness to abandon old shibboleths both at home and abroad was a major factor in bringing about the end of the conflict. The three volumes, while not always an easy read, are the outcome of considerable research and expertise in both primary and secondary sources and will repay careful study.  相似文献

The final volume of the Foreign relations series of documents on Indochina during the Nixon and Ford presidencies is not as detailed as those which preceded it. However, the documents do not support the view that, once the January 1973 Agreement between the Democratic Republic of (North) Vietnam and the United States had been concluded, the US was prepared to accept DRV's hegemony over the rest of Indochina, provided only that there was a ‘decent interval’ before it occurred. In fact, both the Nixon and Ford administrations did seek to prevent this from happening, but found their hands tied by congressional opposition. In the case of Cambodia, the United States also found itself the victim of its own illusions about the willingness of the People's Republic of China to support an alternative government led by the former ruler, Prince Norodom Sihanouk. Following the more or less total collapse of American policy in April 1975, some interesting ‘post‐mortems’ from various government departments on the history of US involvement in Indochina are also printed in the volume under review.  相似文献

Based upon recently published American documents, this article examines the United States's policy towards the crisis which led to the breakup of Pakistan and the formation of Bangladesh at the end of 1971. President Richard M. Nixon and his national security advisor, Henry Kissinger, deliberately kept this policy closely under their control and were guided more by geopolitical than by moral considerations. In particular, they were anxious to forge a new relationship with communist China and the contribution of the Pakistani president, Yahya Khan, in facilitating contacts between the US and China were greatly appreciated by the two men. Nixon's visceral dislike of the Indian prime minister, Mrs Indira Gandhi, also contributed to a degree of myopia and misperception regarding India's objectives and their possible consequences. As the conflict between the rebels in East Pakistan (Bangladesh) and the central government deepened and Indian involvement on the side of the rebels grew, Nixon and Kissinger saw another threat in the shape of Soviet military and moral support for India. An Indian victory would not only increase India's prestige and position vis-à-vis those of Pakistan, but tip the global balance of power towards the Soviet Union and away from the United States. Frantic diplomatic efforts, combined with scarcely veiled threats, finally succeeded in preventing the total disintegration of Pakistan, but there is some doubt as to whether this was likely in the first place and whether US policy was successful in relation to either China or the Soviet Union.  相似文献
