North Korea says missile launches were warnings against U.S.-South Korea military exercises

A leaked U.N. report found that North Korea allegedly stole about $2 billion using cyberattacks to fund its weapons program. This comes after the country fired two missiles Tuesday in what leader Kim Jong Un called a "warning" against the U.S. and South Korea for conducting joint military exercises. Gordon Chang, author of "Nuclear Showdown: North Korea Takes On the World," joined CBSN to discuss the state of relations between the U.S. and North Korea.
