The conflict in the Middle East needs to be solved for the same reasons. It is necessary to reach a two-states solution built on international law for sustainable peace and development and it can only be achieved through joint efforts by the international community.

I think what the Nobel committee is doing is going beyond war and looking at what humanity can do to prevent war. Sustainable management of our natural resources will promote peace.

When I think about the world I would like to leave to my daughter and the grandchildren I hope to have it is a world that moves away from unequal unstable unsustainable interdependence to integrated communities - locally nationally and globally - that share the characteristics of all successful communities.

If you believe that health care is a public good to be guaranteed by the state then a single-payer system is the next best alternative. Unfortunately it is fiscally unsustainable without rationing.
