<p>Gender is widely recognized as an important and useful lens for the study of International Relations. However there are few books that specifically investigate masculinity/ies in relation to world politics. </p><p> Taking a feminist-inspired understanding of gender as its starting point the book: </p><p> - explains that gender is both an asymmetrical binary and a hierarchy;</p><p> - shows how masculinization works via 'nested hierarchies' of domination and subordination;</p><p> - explores the imbrication of masculinities with the nation-state and great-power politics;</p><p> - develops an understanding of the arms trade with commercial processes of militarization.</p><p> Written in an accessible style with suggestions for further reading this book is an invaluable resource for students and teachers applying 'the gender lens' to global politics.</p>
