“Security, stability and prosperity will depend on the application of the multi-sum security principle that captures the multi-dimensional aspects of security and insists on the centrality of global justice for lasting security.”

1963, Remarks Prepared for Delivery at the Trade Mart in Dallas
Context: Our security and strength, in the last analysis, directly depend on the security and strength of others, and that is why our military and economic assistance plays such a key role in enabling those who live on the periphery of the Communist world to maintain their independence of choice. Our assistance to these nations can be painful, risky and costly, as is true in Southeast Asia today. But we dare not weary of the task. For our assistance makes possible the stationing of 3-5 million allied troops along the Communist frontier at one-tenth the cost of maintaining a comparable number of American soldiers.

Truman Library address (2006)
Context: No nation can make itself secure by seeking supremacy over all others. We all share responsibility for each other’s security, and only by working to make each other secure can we hope to achieve lasting security for ourselves.
— And, I would add that this responsibility is not simply a matter of States being ready to come to each other’s aid when attacked — important though that is. It also includes our shared responsibility to protect populations from genocide, war crimes, ethnic cleansing and crimes against humanity — a responsibility solemnly accepted by all nations at last year’s UN world summit. That means that respect for national sovereignty can no longer be used as a shield by Governments intent on massacring their own people, or as an excuse for the rest of us to do nothing when heinous crimes are committed.
