SLOWING DOWN TO KEEP THE LEAD IN MILITARY TECHNOLOGY

We develop a model of military technology competition among states. States can choose to introduce new military technology, mimic rivals’ level of technology, or withdraw from the contest. States can choose to implement any level of technology within their current feasible technologies. We find that states with significant technological leads should sometimes withhold new technologies, only strategically releasing them to trump rivals’ efforts. We develop the model by refining Admiral Jackie Fisher’s roughly articulated concept of ‘plunging’. We then use this refined argument to reanalyze the case of naval rivalries among European powers between the Crimean War and the First World War. Finally, we conclude by discussing the model’s implications for current US military force structure planning.     

Country Survey XIII: Japan's security posture and defense industry prospects

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 Double‐digit defense spending increases that were common in the 1980s have been replaced by annual increases lower than present inflation rates, resulting in negative real growth in the country's defense budget.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.     

Private security contractors and international humanitarian law—a skirmish for recognition in international armed conflicts

In recent international armed conflicts private security contractors (PSCs) have played an ever increasing role and military advisors and tribunals are facing the dilemma of assessing the primary and secondary status of PSCs under international humanitarian law. In this article the misconception that PSCs are necessarily mercenaries will be dispelled. The possibility that PSCs might be categorised as combatants or civilians will then be explored. The conclusion is that where they are incorporated into the armed forces of a state, PSCs might attain combatant status. However, given that states are reluctant to formally incorporate PSCs into their armed forces, they will most likely remain essentially civilian. Their degree of participation in hostilities will determine whether they retain their immunity under international humanitarian law from attack and prosecution (as civilians) or whether they are rendered unlawful belligerents.     

Do migrant remittances react to bouts of terrorism?

This paper examines the short-run behaviour of migrant remittances in the face of terrorism. Using monthly data for post 9/11 terrorist attacks in Pakistan, the study finds evidence of increase in the volume of remittances sent from abroad. This increase is evident in the aggregate, as well as for the three main source regions of North America, the Persian Gulf and Europe. The positive association holds for all the top five migrant-hosting countries of Pakistan. The findings point in favour of an altruistic behaviour of migrant remittances at the macroeconomic level.     

Inside the Iraqi State Records: Saddam Hussein, ‘Irangate’, and the United States

This article uses captured Iraqi state records to examine Saddam Hussein's reaction to US arms to sales to Iran during the Iran–Iraq War (the Iran/Contra scandal). These records show that ‘Irangate’ marked a decisive departure in Saddam's relations with the United States. Irangate reinforced Saddam's preexisting suspicions of US policy, convincing him that Washington was a strategic enemy that could not be trusted. Saddam concealed his anger to preserve a working relationship with the Reagan administration, but this episode nevertheless cemented his negative views of the United States and forged a legacy of hostility and mistrust that would inform his strategic calculus for years to come.     

Four new takes on Wilson,World War I,and the making of the post-war order

The books under review here, by Robert F. Hannigan, John A. Thompson, Trygve Throntveit, and Adam Tooze, offer an interpretation of Wilsonian internationalism and what happened to it in the 1920s. For Tooze and Hannigan, Wilsonianism was primarily a project to attain American predominance in the world. For Throntveit, Wilsonian internationalism constituted a pragmatic yet radical effort to end competitive power politics. Thompson disagrees with these arguments and asserts that the key to understanding US policy lay in how US leaders conceptualized American power. Thompson’s interpretation is especially compelling in explaining why the United States failed to engage itself more assertively in international affairs in the 1920s – a failure Tooze suggests undermined the viability of the postwar international system.
