Theories of international relations and the studies of modern diplomatic history have been most concerned about the interactions among major powers in international system. The strategies of powerful states have been widely discussed by international relations scholars and the strategic concerns of weak states have not received adequate attention. This book endeavours to analyse the rather neglected security problems regarding weak states and their perspectives in deterring and resisting security threats that they perceive from neighbouring strong powers. Case studies of Bangladesh, Jordan and Finland and their relations with India, Israel and Russia are taken into account because they represent examples of weak states facing persistent threats from more powerful neighbouring states. The book also focuses on the usefulness of Paul Schroeder's category of state strategies and tactics. The objective of this book is to develop a fundamental understanding and explanation regarding the issues pertaining to weak states behaviour in some detail and the reasons why weaker states adopt self-defence strategies vis-à-vis stronger neighbours.
