Optimal versus required defence expenditure: The case of the Greek-Turkish arms race

The aim of this paper is to indicate the extent to which the arms race against Turkey, in which Greece and Cyprus have been entangled, imposes a defence expenditure burden that is tough for the two allies to bear. To do so we have resorted to evaluating the optimal military expenditure for the two countries, allied in the context of the Integrated Defence Doctrine, which is compatible with the constraints imposed by the resources of their economies. All experiments and scenarios examined lead to the conclusion that the current defence burden of the two allies seems to be driving their economies beyond capacity limits. The fact remains, however, that under the circumstances, a one-sided disarmament policy like the one currently followed by Greece, is a risky choice given that the long-term armament programmes pursued by Turkey, whose role in this arms race has been proven as leading, leave very small room to the Greek and Cypriot sides to reduce their own defence expenditure.     

GLOBALIZING REAGAN'S INF TREATY

When it was concluded more than a quarter century ago, the Intermediate-Range Nuclear Forces (INF) Treaty between the United States and the Soviet Union was hailed as a disarmament watershed, eliminating entire classes of nuclear missiles from the arsenals of the arms-racing Cold War superpowers. Over the intervening decades, there have been repeated calls to convert this legacy treaty into a new international norm against nuclear and missile proliferation by broadening it into a global prohibition on ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. Indeed, variations on this proposal have been knocking around for so long and with so little success that the entire concept has come to be dismissed by many knowledgeable insiders as something of a farce. Looking beyond its inauspicious pedigree, however, this viewpoint suggests that the time is opportune for Washington to give the idea a fresh look. Drawing on a detailed review of the history of “Global INF” and an analysis of the contemporary context, the author recommends that the Obama administration consider a simple declaratory approach that promises modest initial benefits, avoids previous and foreseeable pitfalls, and plausibly lays a solid foundation for achieving significant long-term progress.
