The core principle underlying the strategy of nonproliferation ? acceptance of a two tier international nuclear order - has become unsustainable.

Are there alternative strategies for managing nuclear weapons in the region? Should the presence of nuclear weapons in Northeast Asia necessarily be seen in exclusively negative terms, as many experts believe?
