AIR FORCE ACADEMY, Colo. (AP) - Vice President Joe Biden says this year's Air Force Academy graduates are entering a changed world that requires the nation to decide when it should act alone and when to build coalitions.
In a speech at the academy commencement Wednesday, Biden told the graduates their country needs them to be strategic thinkers as well as warriors.
Biden echoed President Barack Obama's remarks earlier in the day, saying the U.S. must approach foreign policy with "wisdom and humility" when deciding when to get involved.
Speaking at West Point's graduation, Obama urged restraint before any new military engagements.
Biden says the nation needs a strong economy, a reputation for defending human rights and a strong presence in the Pacific to remain a global power.
Nearly 1,000 cadets are graduating from the academy.
