Brazilian National Defence Policy: foreign policy,national security,economic growth,and technological innovation

ABSTRACT

With the world’s ninth largest economy and comprising nearly 60% of South America’s GDP, 47% of its territory, and 49% of its population, Brazil has become a regional power and an important actor in world affairs over recent decades. This scenario has led the government to re-evaluate its role in the world order, resulting in the enactment of the National Defence Policy, whose objective was to consolidate the country as a regional power while at the same time addressing national security issues, promoting economic development through a series of defence programmes, restructuring the defence industrial base, fostering innovation through technology and knowledge transfer to Brazil, and indigenous research and development. However, the policy’s implementation suffers from several challenges discussed in this article, which may test the capability and competence of Brazilian policymakers, military, industrialists, and other individuals and organisations involved in its implementation.     

The subversion of the Bulgarian defence system – the Russian way

Russia has long been pursuing an intended and calculated policy of keeping enough influence in Bulgaria in order to have control over national decisions. Together with the economic, energy, political and information tools used by Russia in its hybrid war against Bulgaria and in its bid to achieve an enduring “state capture,” defence is also a distinct target of Russian subversion now. A list of noticeable subversive actions with tangible effects can be summarised, ranging from fuelling division and manipulating public opinion, preventing the strengthening of the NATO position in the Black Sea, sabotaging defence reform to various options of subverting the modernisation of the Bulgarian Armed Forces and seeking new ways to keep legacy Soviet military equipment in operation as long as possible. This issue must be urgently addressed both nationally and in NATO.     

Feeding the Lion: China and defence development in African states

ABSTRACT

In analysing trends in Chinese defence engagement and their impact on defence development in African states, it is important to consider both China's changing policy priorities and its capabilities for the provision of defence support. China's international ambitions and its economic development contribute to its emergence as a key supporter of defence capability development in Africa, occupying a crucial niche as a provider of support, particularly arms transfers, appropriate to evolving local requirements. The economic and politico-military imperatives driving China's engagement of Africa, which stem from its economic reforms and re-emergence as a great power, are facilitating defence modernisation by accelerating the introduction of modern arms in substantial quantities. The commercial importance of arms exports and the growing importance of strategic ties strongly situate China to help sustain processes of defence capability development in African states over the long term.     

城市防空中目标优化分配的模糊聚类分析

定性和定量相结合,利用模糊聚类分析法确定目标的优先防护次序.先构造城市防空中需掩护的目标体系;再依据目标权重建立多因素模糊关系矩阵,导出等价矩阵;最后计算出基于给定参数λ的需防护目标的优先次序,得出目标分类聚类图.变模糊的、复杂的问题为直观的结论,为指挥员合理分配兵力兵器提供可靠的依据,从而最大限度地发挥防空兵器的作战效能.
