US President Barack Obama told CBS on Tuesday that his country is preparing to defend itself against North Korea, by developing a missile defense system and forming a shield against “The erratic country.”
"One of the things that we have been doing is spending a lot more time positioning our missile development systems, so that even as we try to resolve the underlying problem of nuclear development inside of North Korea, we're also setting up a shield that can at least block the relatively low-level threats that they're posing now," Obama said.
