Two stand-alone articles by Frank Lehrbass and Valentin Weinhold on Russian risk-taking and by J. Paul Dunne and Ron P. Smith on the top-100 firms in the global arms industry are followed by a three-article symposium on Greece and Turkey. The first of these, by Eftychia Nikolaidou, examines the role of military expenditure and arms imports in the Greek debt crisis; the second, by Christos Kollias, Suzanna-Maria Paleologou, and Andreas Stergiou, looks at the economic constraints on Greek military expenditure; and the third, by Gulden Ayman and Gulay Gunluk-Senesen, explores Turkey's security policies and expenditures during the reign of the AKP party.
