What if the greatest threats to national security weren’t missiles or cyberattacks, but loneliness, misinformation and eroding trust? Human security, encompassing the safety and dignity of individuals, has long been relegated to the margins of national security policy, yet it increasingly shapes a nation’s strategic resilience. Human security was framed initially around seven pillars: economic, food, health, environmental, personal, community and political security. Labour shortages—driven by ageing populations, burnout and uneven education outcomes—are becoming national security concerns as much as economic ones. None of this is to suggest that traditional national security threats are less important.
