NEW YORK (AP) -- Vice President Joe Biden has issued a strong defense of President Barack Obama's foreign policy record and suggested that Republican Mitt Romney doesn't understand the role of contemporary commander in chief.
Biden delivered a campaign foreign policy speech Thursday at New York University.
The vice president said Obama had met the foreign policy challenges facing the United States in the 21st century, including ending the war in Iraq and ordering the mission that killed Osama bin Laden.
He said Romney's foreign policy vision is stuck in the Cold War-era.
Romney advisers held a conference call before Biden spoke to criticize Obama's record on foreign policy.
John Lehman, Navy secretary in the Reagan administration, accused Obama of "a gross abdication of leadership" that could have practical and political consequences.
