In short, U.S. plans for expanded military activities in space, especially when combined with the strategic doctrine of coercive prevention, are perceived internationally as presenting a serious problem, but the United States will not acknowledge any legitimate reason for concern. It has unilaterally withdrawn from the ABM treaty and is refusing to discuss, let alone negotiate, new rules for military space activities in the C.D., in the U.N. Committee on the Peaceful Uses of Space (COPUOS), or in any other multilateral forum. U.S. efforts to unilaterally rewrite the rules for space in support of a national security strategy of coercive prevention could provoke a major international policy confrontation in which the United States would be isolated unless it restores a diplomatic dimension to its space security policy and considers more collaborative steps to protect its own space assets without threatening other countries.
