The Origin of Alliances: From Sparta to the EU’s Solidarity Clause

Abstract

According to the International Relations theory known as Realism, interstate interactions, whether ancient or modern, are motivated by the pursuit of hegemony of individual states, which act as monolithic groups in articulating their foreign policy decisions. The application of Realism to the study of Spartan foreign policy in the third century BC shows the validity of this theory in explaining certain aspects of ancient interstate interactions, as illustrated by the two alliances discussed in this article. The first, earlier alliance, between King of Macedonia Antigonos Gonatas and Sparta and some Peloponnesian cities, was made in response to the threat posed by King Pyrrhus of Epirus who was set on conquering them. The later alliance, between Sparta and other states, was made to stop the ambitions of King Antigonos Gonatas who controlled many cities of the Peloponnese and sought to conquer the whole of Greece. In forging such alliances, according to the Realist view, the states acted as large monolithic groups, yet a broader assessment of the available evidence shows the presence of smaller, subtler networks of individuals, which were paramount in articulating important foreign policy decisions. The comparison of Spartan decision making with the activation in 2009 of the EU’s Solidarity Clause, included in Article 222 of The Treaty on the Functioning of the European Union (TFEU), indicates that the activation of this clause too required the consensus of several European governing bodies. By bringing to light the critical role played by smaller networks of power in foreign policy decision making in the ancient and the current-day EU alliances, this article exposes both the merits and the limits of the Realist international relations theory.     

On the geochemistry of gases and noble gas isotopes (including 222Rn) in deep crustal fluids: the 4000 m KTB-pilot hole fluid production test 2002–03

The concentrations of H₂, O₂, CO₂, and concentrations and isotopic composition of the noble gases (including ²²²Rn), N₂, CH₄, and higher hydrocarbons dissolved in 4000 m deep‐seated fluids from a 12‐month fluid production test in the KTB pilot hole were analyzed. This determination of the gas geochemistry during the test in combination with the knowledge of the hydraulic data provides relevant information about the fluid hydraulics of the deep system. All gas concentrations and isotopic signatures, except for ²²²Rn, showed constancy during the course of the test. This, in combination with large fluid flow rates at a moderate water table drawdown, imply an almost infinite fluid reservoir in 4000 m depth. From the change in ²²²Rn‐activity as a function of pump rate, the contribution of smaller and wider pores to the overall fluid flow in an aquifer can be deduced. This ²²²Rn‐activity monitoring proved therefore to be a valuable instrument for the qualitative observation of the scavenging of pore and fracture surfaces, a hydraulic feature invisible to standard hydraulic testing tools. The observance of this scavenging effect is due to (i) the continuous on‐line geochemical monitoring, (ii) the durability of the test, (iii) a change in pump rate during the course of the test, and (iv) due to the short half‐life of ²²²Rn. The fluids have a 5.9% mantle He component, and a δ²¹Ne excess of 14%, and a noble gas model age of about (5.5–6.2) ± 2.0 Myr. The mean N₂/Ar‐ratio of 516 and δ¹⁵N‐data of about +1.5‰ indicates sedimentary or metamorphic origin of N₂. The hydrocarbons, amounting to 33 vol.% in the gas phase, are derived from thermal decomposition of marine organic matter of low maturity. But a key question, the identification of the potential source region of the fluids and the migration pathway, is still unidentified.
