Defense budgets in Japan have been complicated compromises from numerous inputs ‐ including threat perceptions, domestic industrial/technological base development, support for the bilateral security treaty with the United States and internal bureaucratic politics ‐ but with the fall of the former Soviet Union, the clearest justification for higher spending disappeared. Double‐digit defense spending increases that were common in the 1980s have been replaced by annual increases lower than present inflation rates, resulting in negative real growth in the country's defense budget. Domestic economic problems and consistent government pressures for smaller budgets have further slowed annual growth in total spending and have contributed to lower procurement budgets. As a result, the domestic Japanese defense industry is facing far more constrained conditions from the growth years of a decade before.

Government policymakers are examining Japan's regional security environment as well as its alliance with the United States to determine the appropriate course for the country to take in the coming years. The formal security treaty with the United States is likely to remain a major element of government positions, but other aspects of the country's overall security posture are open to debate. Perceptions of a reduced threat environment are fueling additional pressures for defense budget cuts.

The domestic defense industry seeks means to assure its survival in domestic defense markets in this constrained environment. Expansion into overseas markets to offset declining domestic markets is an option that currently is constrained by policy restrictions on arms exports. Industry is advocating re‐examination of those policies and unlike earlier years, government appears willing to respond positively but cautiously to this lobbying.  相似文献

The misuse of biological research is increasingly becoming a prominent policy concern. One regulatory measure that has gained considerable support over the last few years in response to this is voluntary self-governance by the scientific community, and in particular codes of conduct. This article charts the rise of the policy debate on codes, highlighting the involvement of the scientific community. Shifting the focus from policy to practice, it explores the effectiveness of codes of conduct as a regulatory measure by examining our experiences of how another voluntary self-governance regime in the biosciences has worked in practice. Noting limitations with voluntary self-governance as a regulatory tool to prevent misuse, this article includes a reflection on the attention paid to codes of conduct in policy discussions, arguing that there are at least three possible interpretations.  相似文献

British attitudes towards military intervention following the campaigns in Iraq and Afghanistan have undergone what appears to be considerable change. Parliament has voted against the use of Britain's armed forces in Syria and the public are unenthused by overseas engagement. Conscious of the costs and the challenges posed by the use of British military power the government has been busy revamping the way it approaches crises overseas. The result is a set of policies that apparently heralds a new direction in foreign policy. This new direction is encapsulated in the Building Stability Overseas Strategy (BSOS) and the more recent International Defence Engagement Strategy (IDES). Both BSOS and IDES set out the basis for avoiding major deployments to overseas conflict and instead refocuses effort on defence diplomacy, working with and through overseas governments and partners, early warning, pre-conflict prevention and post-conflict reconstruction. Developing a number of themes that reach from across the Cold War to more contemporary discussions of British strategy, the goal of this special edition is to take into account a number of perspectives that place BSOS and IDES in their historical and strategic context. These papers suggest that using defence diplomacy is and will remain an extremely imprecise lever that needs to be carefully managed if it is to remain a democratically accountable tool of foreign policy.  相似文献

The Soviet-led Council for Mutual Economic Assistance member, Central European countries found themselves in a difficult political and economic situation after the collapse of the Soviet Union. Three post-Eastern Bloc countries formed the Visegrad Group to strengthen their ties to the West, but the need for foreign investment, job creation and technology transfer was urgent.

This is when military modernisation also came into the picture and the counter-trade—as known as offset—as a tool to help these economies. A trade practice which was meant to energise these economies via defence acquisitions linked economic programmes.

Two Visegrad Group member countries, Hungary and the Czech Republic decided to sign offset agreement with the defence firm SAAB to license Gripen fighter aircrafts. This study intends to analyse if these deals were able to help governments to reach their objectives or the two countries were unable to take advantage of the offset programmes.  相似文献

ABSTRACT

This paper examines the importance of closer co-operation in defence-related procurement. Led by the decision that Belgium will lead the procurement of 12 Mine CounterMeasures Vessels (MCMV), the case of a potential Belgian naval construction cluster is discussed. The feasibility of a potential cluster is investigated by looking at key elements of a successful naval construction cluster, the Dutch naval construction cluster, and comparing those key elements to the current Belgian situation. Forming a sustainable Belgian naval construction cluster will be difficult. Most of the procurement process of the MCMVs is set on a European tender. In the long run, due to the absence of both a launching customer and leader firms, no party is able to carry the cluster with investments and knowledge spill-overs. In order to keep public support for large defence-related investments, clustering around the MCMV integration system and proactive cluster support is recommended.  相似文献

ABSTRACT

What Rudyard Kipling called the ‘campaign of lost footsteps’ was the longest campaign fought by the Victorian army. The conquest of Upper Burma, an area of 140,000 sq. miles with a population of four million, took only three weeks in November 1885 and was accomplished with minimum cost. However, the removal and deportation of the Burmese King and dismantling of all traditional authority dismantled led to growing resistance to British rule leading to an increasingly difficult guerrilla war. Though the Burmese guerrillas were characterised by the British as mere bandits or dacoits, many were former soldiers along with Buddhist monks. The extremely difficult nature of campaigning in the terrain and climate of Burma was not sufficiently appreciated by the War Office, who viewed the conflict as a ‘subaltern’s war’ and ‘police’ work. Intended regime change was also not accompanied by any consideration of the likely implications. Prolonged insurgency necessitated deploying a force far larger than originally intended; though order was finally secured by 1895, the campaign proved destructive of Burmese society while British recruitment of hill tribes into the police and armed forces sowed the seeds for future divisions.  相似文献

ABSTRACT

The paper summarises the evolution of the iron triangle of the mutual relationships amongst the ministry of defence, defence industry, and the political elite in the post-communist Czech Republic in 1990-2020. The essay stresses the oddness of this relationship. On the one hand, the government is bound by a partnership to the Defence and Security Industry Association of the Czech Republic (DSIA), a lobbying group of more than 100 organisations that conduct business in defence and security sector in Czechia. Yet, since its creation in 2000, this assemblage of industries within DSIA's market position is falling, in fact. Neither political parties in power, nor the governments have been able to support national defence industry through the small military. Just a few DSIA national members are able to compete internationally with their cutting-edge products. Others have evolved into middlemen trading intime-expired Czechoslovak equipment retired from the Czech Armed Forces.  相似文献
