U.S. Vice President Joe Biden is telling an international security conference that there's still time for diplomacy to succeed in resolving concerns over Iran's nuclear program — but he's insisting that it's up to Tehran to show good faith.
Biden's comments on Saturday came a few days after Iran, in a defiant move ahead of new talks expected later this month with leading world powers, announced plans to vastly increase its pace of uranium enrichment. That can be used to make both reactor fuel and the fissile core of warheads.
Biden told the Munich Security Conference that "there is still time, there is still space for diplomacy backed by pressure to succeed." He didn't specify any timeframe.
He insisted that "the ball is in the government of Iran's court."
