“Flectas non frangas”: revisiting early twenty-first century UK–US defense relations (2000–2005) after five years

Adopting the analytical framework of the established interpretive “schools” of Anglo-American relations, this article offers several reflections on UK–US defense relations as they occurred over the significant years of 2000–2005. During those years, trajectories were established on which UK–US defense relations continue to travel today and outcomes emerged which are still being navigated. This article concludes that the Latin phrase, “Flectas Non Frangas” (essentially translated as: “Bend not Break”), is the most appropriate to adopt to characterize the developments undergone in recent UK–US defense relations. Many historical and strategic lessons with contemporary relevance are drawn.     

A new reformulation approach for the generalized partial covering problem

In this paper, we consider a situation in which a group of facilities must be constructed in order to serve a given set of customers, where the facilities might not be able to guarantee an absolute coverage to the different customers. We examine the problem of maximizing the total service reliability of the system subject to a budgetary constraint. We propose a new reformulation of this problem that facilitates the generation of tight lower and upper bounds. These bounding mechanisms are embedded within the framework of a branch‐and‐bound procedure. Computational results on problem instances ranging in size up to 100 facilities and 200 customers reveal the efficacy of the proposed exact and heuristic approaches. © 2005 Wiley Periodicals, Inc.

Keeping David From Bathsheba: The Four-Star General’s Staff as Nathan

Readers of reports on ethical failures by four-star general officers must wonder, “Don’t they have staffs to ensure that the general follows ethics rules?” The Department of Defense publishes robust ethics guidance in several documents; however, a staff’s best efforts to implement this guidance may fail to make an impression on a senior leader who is susceptible to the “Bathsheba syndrome,” an allusion to the biblical account where the prophet Nathan rebuked King David for his moral failings. This paper proposes a methodology to enable senior headquarters staffs to play the role of Nathan in supporting ethical behaviors by high-level officers. It examines the mechanisms that embed ethical behavior within members of those staffs in carrying out their three principal roles of advising, scheduling, and transporting the four-star officer. The authors offer a framework based on an ethical infrastructure of organizational climate that focuses the staff’s daily efforts to mitigate risk across seven ethical “danger areas” that threaten ethical failures by senior officers.     

Attrition modeling in the presence of decoys: An operations-other-than-war motivation

Under various operational conditions, in particular in operations other than war (OOTW) or peacekeeping, an intervening force, here Blue, must occasionally engage in attrition warfare with an opposing force, here Red, that is intermingled with noncombatants. Desirably, Red armed actives are targeted, and not the unarmed noncombatants. This article describes some simple Lanchesterian attrition models that reflect a certain capacity of Blue to discriminate noncombatants from armed and active Red opponents. An explicit extension of the Lanchester square law results: Blue's abstinence concerning the indiscriminate shooting of civilians mixed with Red's is essentially reflected in a lower Blue rate of fire and less advantageous exchange rate. The model applies to other situations involving decoys, and reflects the value of a discrimination capability. © 1997 John Wiley & Sons, Inc. Naval Research Logistics 44 : 507–514, 1997     

Testing or fault-finding for reliability growth: A missile destructive-test example

A new piece of equipment has been purchased in a lot of size m. Some of the items can be used in destructive testing before the item is put into use. Testing uncovers faults which can be removed from the remaining pieces of equipment in the lot. If t < m pieces of equipment are tested, then those that remain, m₁ = m − t, have reduced fault incidence and are more reliable than initially, but m₁ may be too small to be useful, or than is desirable. In this paper models are studied to address this question: given the lot size m, how to optimize by choice of t the effectiveness of the pieces of equipment remaining after the test. The models used are simplistic and illustrative; they can be straightforwardly improved. © 1997 John Wiley & Sons, Inc. Naval Research Logistics 44: 623–637, 1997     

An extreme-point approach for obtaining weighted ratings in qualitative multicriteria decision making

Many attempts have been made in the past to obtain estimates for the weights and ratings values of a multicriteria linear utility function. In particular, the problem arises when both criteria importance and alternatives' ratings are expressed in a qualitative ordinal manner. This article proposes an extreme-point approach for obtaining the overall ratings in the presence of ordinal preferences both for the criteria importance and the alternatives' rankings. In particular it is shown that Borda's method of scores is obtained as a special case. © 1996 John Wiley & Sons, Inc.     

A suboptimality bound for permutation policies in single machine stochastic scheduling

A general class of single machine stochastic scheduling problems incorporating precedence constraints is modelled as a family of competing Markov decision processes. A bound on the optimal return yields a suboptimality bound for permutation policies. This in turn leads to a generalised “used better than new” principle as a (highly intuitive) sufficient condition for the optimality of a permutation policy in the class of all (preemptive) policies. © 1995 John Wiley & Sons, Inc.     

Aircraft sortie effectiveness model

A mathematical model describing the sortie of a single aircraft under enemy threats, attacking a single passive target, is developed. Emphasis is placed on the determination of the probabilities associated with the various events in the sortie. These probabilities are then used to derive appropriate measures of effectiveness. The optimum sortie time is analyzed.     

Saddam versus the inspectors: the impact of regime security on the verification of Iraq’s WMD disarmament

The discovery that Iraq had no weapons of mass destruction (WMD) in 2003 raised the question of why Saddam had prevented UN weapons inspectors from fully accounting for his disarmament. The leading explanation for Saddam’s behavior is that he valued ambiguity as part of a strategy of ‘deterrence by doubt’. This article argues that Iraq’s obstruction of inspectors in the late 1990s was motivated by his desire to shield Iraq’s regime security apparatus from UNSCOM’s intrusive counter-concealment inspections. The failure to understand how strongly Saddam’s concerns about his personal safety drove Iraq’s contentious relationship with UNSCOM set the stage for the invasion of Iraq in 2003.     

What explains the failure of U.S. army reconstruction in Afghanistan?

ABSTRACT

This author wrote his doctorate thesis on post-conflict army reconstruction, submitting it in 2011. Continued research on the subject in the intervening seven years indicates that his theoretical propositions can be refined and improved. This article examines refinements to the model, and then applies those refinements in detail to the Afghan case. In so doing, it shifts the focus from potentially altruistic state-building to a case that was driven by pure national-strategic interests. Issues surrounding the liberal peace ideology dominate recent army reconstruction in conflict-affected states. The liberal peace underpinning is of supreme importance, so much so that in many discussions, it is internalised and accepted virtually without thought. This paper will advance the body of knowledge by establishing, for the first time, a theoretical basis for the widespread failure of army reconstruction in Afghanistan. The empirical basis builds on extensive previous research by other scholars. The resulting model can also be applied to better explain outcomes in other similar cases.
