WASHINGTON (AP) — The Pentagon said Tuesday its spending plan for 2015 would begin to reshape the military after more than a decade of war without lessening America’s commitment to support European allies at a time of tension with Russia.

The proposed $496 billion budget reflects what Defense Secretary Chuck Hagel calls a choice to field a smaller but more modern force rather than a larger one less prepared for combat. Some in Congress, however, see that as an approach that weakens U.S. capabilities in a period of growing uncertainty in Europe and Asia.
