This week's Thought proposes four key routes towards 'Loving your enemy', including a gradual transition from national to international law. This would mean justice not being constrained by national borders, so we could look forward to a system of international civil law enforcement replacing reliance on military force to resolve criminal outbreaks — it would also help us to resolve the challenges of climate change. Another element is restorative justice: Nelson Mandela and Desmond Tutu showed the world that such a system can provide a pathway to peace in the most challenging of circumstances. These initiatives, based on an understanding of unconditional love and an equitable sharing of resources, can provide a way forward from our current woes.
