Peace, real, lasting peace, is not a product of disavowing war, or thinking peaceful thoughts.
Nor is it the product of negotiated settlements.
Peace is the product of winning the war brought against you, with sufficient force to prevent any ideas of trying it again.
World war II was the direct result of the negotiated settlement imposed following WWI.
The current Korean troubles are the product of negotiating away our efforts in the original Korean War.
Consider, on the other hand our victories over Japan and Germany and how decisive they were , and how good and peaceful an ally each has been following that victory.
