U.S. Defense Secretary Leon Panetta is likely this week to unveil the results of the Pentagon’s strategic review of U.S. roles, missions and worldwide posture, a defense official said today.

When the review was announced last year by Panetta’s predecessor as defense secretary, Robert Gates, he said it was important for the public and Congress to get a full understanding of strategic choices for the U.S. military as it faced $450 billion in additional reductions through 2021, including about $261 billion through 2017.
