Domestic factors play an important role in the formulation and evolution of a country's foreign and security policy. This is clearly seen in the case study of a Soviet successor state, Ukraine. The article brings together in seven sections theory with the key domestic factors that influence Ukrainian security policy, such as economics, energy, national identity, elites and political parties. The article provides an insight into how these domestic factors influence the course of Ukrainian security policy which is striking a balance between the twin extremes of Soviet re‐integration, which would be tantamount to the loss of independence, and nationalist maximalism which seeks to place as much distance as possible between Ukraine and Russia.  相似文献

The Fisher naval revolution of 1904–10 represented a deliberate attempt to achieve defense transformation to bolster Britain's pretensions to global naval supremacy. The vision called for smaller, more capable forces to do the work of larger, more expensive conventional formations. It consisted of three main elements. First, the replacement of the traditional station fleet system for protecting overseas interests by rapid deployment forces comprised of battlecruisers that could be ‘maneuvered’ by wireless to combat specific enemy threats. Second, at home, instead of a sea control strategy based upon a superior battle-fleet, a sea denial strategy based on flotilla defense commanded and controlled from London via wireless. The third element of the Fisher revolution depended upon ‘plunging’, or shaping and directing technological change through a special relationship with armaments firms. A sophisticated information-communications network was integral to the revolution.  相似文献

Peru has battled two major insurgent movements since 1980. Around 25,000 Peruvians have died in this war between the government against the Shining Path and the MRTA. The Peruvian military has been incapable of achieving total victory after several major operations and the capture of just about every major rebel leader. Even worse, after a few years of almost no activity, Shining Path seems to be re-emerging. The last remaining members of this insurgent group have made alliances with foreign terrorist groups, used drug traffic to fund their fight and sweet talked people who are very disappointed and mad at the current Toledo administration, to gain more supporters. Major changes have to occur to prevent both groups from becoming threats to national security and society as a whole, taking the country back to times when around half of the nation was declared to be under terrorist control. The defense budget must be increased to open new bases, buy new equipment and train soldiers better to fight the insurgents more effectively. At the same time, major social changes need to occur; Toledo and his government must gain the trust and sympathy of Peruvians again by working for and with them.  相似文献

South America has gained international media attention due to its ongoing arms race, with politicians and analysts warning about the possibility of war. Nevertheless, since the Chaco War in the 1930s, the region has seldom faced major inter-state wars, all of which have been short-lived and with relatively few casualties. This article will discuss in greater detail the ongoing arms race in South America, portraying it as a race ‘of levels’, with not all countries carrying out massive weaponry purchases. Finally, I will discuss regional geopolitics, geosecurity and integration as part of an analysis regarding the unlikelihood of war.  相似文献

A recent article, ‘Rage Against the Machines’, does a disservice to the debate over what explains counterinsurgency (COIN) success. While it establishes a negative correlation between the diffusion of military mechanization in the state system and COIN success, its theoretical argument does not hold up under close scrutiny and its micro-case comparison of two units in Iraq during 2003–2004 ignores obvious counter-examples and factors that influence COIN success, such as leadership. A deeper inquiry would have revealed that there is much more to COIN success than simply not having access to vehicles.  相似文献

Taking insurgency sponsorship as an instrument states have available for achieving foreign policy objectives, I consider how state-sponsors could best manipulate their support to maximize control of the proxy group. Building on research that models the state-sponsor–insurgent relationship using a principal–agent framework, I identify two key vulnerabilities to which the state-sponsor is exposed: adverse selection and agency slack. As an original contribution to the literature on state-sponsorship of insurgency, I articulate reasons why certain forms of support would be most conducive to overcoming these problems and illustrate how South Africa and Iran used those kinds of support to influence the behavior of their proxies, RENAMO and Hezbollah. Additionally, I consider how this principal–agent analysis of insurgency sponsorship also could apply when the principal is an international terrorist organization such as al Qaeda. Finally, I address the relevance of these ideas to two contemporary conflicts taking place in Syria and the Congo.  相似文献
