This article aims to analyze the Brazilian Defense Policy in terms of its ability to reduce the gap between ends and means. Since 2003, the Brazilian defense policy has evolved along with Brazil’s increased role in the international system. Sustaining this process depends on institutional, economic, and operational conditions that are yet to be fully guaranteed. They require negotiations, reforms, and strategic perspective. By identifying specific challenges emerging from the national security institutional framework, the combat capability building process, the budgetary cycle, as well as from the defense industrial base, we sought to explain their rationale and to offer concrete policy pointers to overcome obstacles. As a general conclusion, the Brazilian defense policy was strengthened by the 2008 National Defense Strategy (END) due to its clearer strategic goals. Bridging the gap between those ends and the proper means is a continuous effort for any given country, but in the case of Brazil it has been addressed with firmer steps since the END, even in the face of harder economic and political conditions.  相似文献

Most counterinsurgency campaigns have featured the use of some form of local defense forces. Such forces have had a somewhat mixed record, both in their usefulness in actually countering insurgents and in their longer-term impact on internal security. This article focuses on historical cases that provide lessons for the best operational and strategic uses of local defense forces and measures to control their activities.  相似文献

随着国际形势的变化以及我国对偷渡犯罪案件打击力度的加强,此类犯罪案件的手段及表现形式也日趋复杂,而立法的滞后性又是必然特点,因此,在司法实践中对于具体犯罪的认定方面就出现了意见不一的现象,也引发了理论界的争议。为此,拟对偷渡犯罪案件中的具体犯罪认定的几个问题进行探讨,以期在交流中获得共识。  相似文献

The US government initiated a Defense Counterproliferation Initiative to address the concern that, in the post-Cold War years, the proliferation of nuclear, biological, and chemical weapons would be widespread and create a significant challenge to the US military’s combat operations. In particular, non-nuclear states might use chemical or biological warfare agents against US forces with the belief that nuclear weapons would not be used against them in retaliation. Following the events of September 11, 2001, defense strategy and policy shifted to a wider view of the threat of adversarial use of “weapons of mass destruction” (WMD) and the term “counterproliferation” was replaced by “combating” or “countering WMD.” Over time, the Defense Department increasingly moved away from counterproliferation principles with the detrimental effect of losing capabilities that US forces still need for contemporary adversaries. This shift has been aggravated by other US government agencies’ use of “counterproliferation” in lieu of what would have been termed “nonproliferation” activities in the 1990s. The loss of clarity within the US government on these terms has led to the inability to focus the “whole of government” on this significant national security challenge. To alleviate this challenge, the US government needs a top-down initiative to refocus policy on the distinctly different aspects of WMD with respect to military combat operations, combating terrorism, and homeland security.  相似文献

Decision-making in defense acquisition programs in the Republic of Korea (ROK) has been problematic, especially in highly advanced complex systems. The highly disputed force modernization program for the ROK Air Force’s fifth-generation fighter, dubbed the Fighter eXperiment, went through extreme turbulence during the type selection phase. The gist of the turbulence became evident through poor institutional coordination within the defense acquisition authorities that eventually forced them to rescind the decision generated from their own yearlong efforts, thus basically shooting themselves on the foot. The paper highlights the background of the program and reviews the institutional elements that influenced the decision-making process, and conclude that the absence of an effective coordination mechanism has made decision-making in complex defense programs even more troublesome.  相似文献
