The book's central argument dismantles the traditional separation of 'women's issues' from the hard-edged realm of international relations. It reveals how societal violence against women, often perceived as a private matter, is demonstrably correlated with a state's proclivity for external conflict. The authors argue that nations with pervasive gender inequality, marked by practices like bride kidnapping, honor killings, and lack of legal protections for women, are statistically more likely to engage in war and international aggression.

'Sex and World Peace' delves into the concept of 'systemic insecurity,' where the subjugation of women creates a culture of violence and instability that permeates all levels of society. This insecurity breeds distrust between nations, hampers economic development, and fuels extremism, ultimately making the world a more dangerous place for everyone, not just women.

The authors provide a hopeful roadmap for positive change. They advocate for a multi-pronged approach involving legal reforms, empowering women in leadership roles, promoting gender-sensitive education, and fostering international cooperation to address the root causes of gender inequality. By tackling the systemic insecurity faced by women, the book posits, we can build a more peaceful and just world for all.
