Biden says U.S. committed to defending allies against North Korean aggression

The U.S. is committed to do what is necessary to defend itself and its allies against aggression from North Korea, U.S. Vice President Joe Biden said on Friday.

Biden made the remarks during a speech at Yonsei University in Seoul, South Korea. Prior to the speech, Biden met with South Korean President Park Geun-hye on various security issues. He said the one overreaching issue of the conversation was the danger presented by North Korea's nuclear program.

"There is one overreaching issue, though, that not only unites Korea and the United States of America, but unites the entire international community - and that is the clear and present danger posed by North Korea's nuclear and missile programs," Biden said. "But no one knows this better than the citizens of the Republic of Korea."

Biden pledged U.S. support for its allies and said North Korea needs to understand that it must demonstrate its full commitment to complete, verifiable, irreversible destruction.

"Let there be no doubt: The United States is committed to do what it takes to defend our allies and ourselves against North Korean aggression - period," Biden said. "The United States and the world have to make it absolutely clear to Kim Jong-un that the international community will not accept or tolerate a nuclear-armed North Korea. That is the consensus that unites us, whether in Tokyo, Beijing, or in Seoul."

Biden said North Korea will never achieve prosperity and security as long as its pursues nuclear weapons.
