When states are under siege, they militarise. Frightened publics want bellicose leaders and higher military spending. Once in power, militarists entrench their institutional and cultural dominance. They fan fears, act tough, and secure public support. Conflicts change popular priorities, not least by reinforcing respect and reverence for macho leaders. Countries threatened by war and terrorism are thus more likely to be governed by men. Peace, therefore, is a hugely important pathway to gender equality.
