WASHINGTON — In the new world created by the dissolution of the Soviet Union, the United States must thwart any power that would threaten America's newly preeminent position and maintain the ability to expand U.S. military forces if a "global competitor" should emerge, according to the Pentagon's chief planning document.

The secret Defense Planning Guidance for the fiscal years 1994-1999 is the first major revision of U.S. national security strategy since the end of the Cold War. And it decisively rejects calls by several lawmakers and world leaders for the United States to share power with many other players on the world stage.

Instead, it outlines the Bush Administration's vision of an America that must use its foreign policy apparatus and its military strength to ensure that its friends--including its longtime European allies and Japan--prosper but do not collude to challenge U.S. influence.

The document also deals with the Bush Administration's politically sensitive opposition to a European security alliance that would exclude the United States and the Administration's support for an arrangement under which the United States would defend Eastern Europe in the event of an attack from the East.

Although the document rejects the assumption of a "policeman" role for the United States, it assumes that Washington will act as an arbiter of all world developments and asserts that the nation should piece together coalitions of convenience to combat developments that threaten U.S. interests.

"While the U.S. cannot become the world's 'policeman,' by assuming responsibility for righting every wrong, we will retain the preeminent responsibility for addressing selectively those wrongs which threaten not only our interests, but those of our allies or friends, or which could seriously unsettle international relations," the classified paper declares.

The Defense Department paper, first reported in Sunday's editions of the New York Times, drew strong reaction from independent experts who have called for greater international cooperation in the wake of the Soviet Union's demise.

"What these Pentagon planners are laying out is nothing but a Pax Americana," said Sen. Joseph R. Biden (D-Del.), a leading member of the Senate Foreign Relations Committee. "Where threats to our stability need to be destroyed, the notion that it can only be done by American military power is outmoded," he added.
