Green Tau issue 125

Defence or security?

16th June 2026

A recent article in the Church Times reported on 

The director of Trinity Centre for Post-Conflict Justice, at Trinity College, Dublin, Dr Jude Lal FernandoI, was among the participants, alongside Anglican church leaders, theologians, church partners, and USPG support. He warned that security concerns were increasingly being prioritised over communities’ basic needs, while hundreds of millions were still living in extreme poverty. “When space for peace and dialogue decreases, the space for violence and oppression increases, especially for women and children,” he said.

This led me to ponder what is the difference between security and defence?

Defence typically refers to the armed services and all their equipment and resources that can be used to repel enemy invasion either of our territory (here in the UK or elsewhere, eg the Falklands) or to support our allies where they are similarly threatened. Such defence would also include defence against cyber attack. 

Security I think is a wider issue that encompasses not just protection from enemy attack or aggression, but is about safeguarding the wellbeing of society as a whole. Thus security issues would include:

  • Food security: can we feed our population? Can we do so largely independent of imports? Do we keep enough in store to weather emergencies and/or supply disruption? Do we pay enough for farmers to survive financially? Do we ensure sufficient incomes so that everyone can afford healthy food? Do we grow the right range of crops (inc livestock) that allows us also to ensure the security of biodiversity and the environment?
  • Health security: are we doing enough to ensure the population is in good health? Do we have enough medical staff, hospital beds, drugs etc? Do we ensure everyone has access to a healthy diet? Do we ensure everyone has access to secure, safe housing – ie accommodation that does not damage their health? Do we ensure everyone has access to dental care? To mental health care? To social care? Do we ensure everyone has access to green spaces essential for mental wellbeing and to sports/ exercise facilities etc essential for physical health?
  • Community security: do we ensure everyone has access to education? That everyone can read, write, calculate and interpret information such that they are not likely to be deceived by false information. Do we ensure enough community spaces that are essential for developing and maintaining good social bonds and networks? Do we do enough to tackle discrimination essential for ensuring equality and harmony within communities?
  • Job security: do we ensure that everyone has access to an appropriate and fulfilling job? Do we ensure everyone has suitable skills and qualifications to enable them to contribute to the economy? Do we ensure sufficient investment in businesses to ensure that they contribute to our wellbeing and do not damage our environment? Do we ensure sufficient investment in our businesses that we can be self-reliant for all essentials? Do we ensure that all stakeholders in a business – staff, customers, nature etc – have a fair share of power and influence in determining the shape and future of the business? Do we ensure that everyone derives a fair benefit from the economy? 
  • Economic security: do we ensure that the economy that supports us financially does so in a way that is fair for everyone, that allows everyone to afford a healthy lifestyle, that protects the environment, that is sustainable over the long term?
  • Energy security: do we ensure we can produce enough energy ourselves to be self sufficient? Do we ensure that we do so at price that is affordable? Do we ensure all buildings, equipment and infrastructure is energy efficient? Do we have measures to ration water if necessary?
  • Water security: do we ensure that everyone has access to sufficient water for a healthy lifestyle? Do we ensure water efficiency at every level to ensure we do not consume more than we extract from our water resources? Do balance the need to maintain water resources against competing demands – whether from industry, agriculture, data centres, domestic users – and do we have measures to ration water if necessary?
  • Environmental security: do we look after the wellbeing of the natural environment to ensure that it can continue to support our wellbeing? Do we see it an essential life support system ensuring clean water supplies, for flood prevention, for clean air, plants to absorb carbon dioxide and provide protection from heat and winds, biodiversity to ensure fertile soils for food and insects for pollination, biodiversity to enrich life and safeguard against future unknowns?
  • Political security: do we ensure fair and democratic forms of government? Do we ensure truthfulness from political parties in both what they say and what they do? Do we ensure fair access to politicians such that those with money and power do not override the views of others? Do we ensure freedom of speech and nonviolent protest? Do we ensure a society where everyone feels valued and everyone feels their voice can be heard?
  • Judicial security: do we ensure a judicial system that provides access to justice to everyone and which is not influenced or used by those with money and power? Do we ensure fair policing? Do we ensure appropriate sentencing that will benefit the whole of society including both those who are victims and those who are offenders? Do we ensure a well designed and resourced custodial system that protects society and ensures the wellbeing of those imprisoned? 
  • Internet etc security: do we ensure that our internet and other communications systems are secure, that they cannot be compromised by error or deliberate intent? Do we ensure there are other systems in place such that if primary systems fail, essential services will be maintained?  Do we ensure that social media etc enhances rather than detracts from our wellbeing?
  • National security: do we ensure all the above which are essential for national security? Do we ensure good diplomatic, trade and welfare relations with other nations such that we work together to ensure peace? Do we ensure through good diplomatic, trade and welfare relations the wellbeing of other nations? – for unless they are at peace and thriving there will always be the risk of conflict and war that will impact us as part of a shred global economy.  Do we with care for the consequences of war, ensure  our nation has appropriately trained personnel and equipment that we can defend ourselves attack?

It seems to me that this bigger vision that the need for security rather than just focusing on defence, is essential if we are to be a happy secure nation. Indeed I’m not sure we gain much from defence if what is being defended doesn’t ensure happiness and well being for everyone.
