Former Texas Republican congressman and presidential candidate Ron Paul argued in a video clip he Tweeted Monday that U.S. foreign policy intentionally keeps North Korea unstable so the communist nation can play the role of international boogeyman.

“We’ve been doing this all this time and it’s almost like [it is] to keep it unstable … The instability is [because] we have promised the South Koreans that, ‘We are going to take care of you. We are going to provide your weaponry. We are going to provide your indirect subsidies. We are going to take care of you and we’re going to make sure that North Korea is held in check.’ Don’t ever talk to them. Don’t ever have an open-door policy … We need an enemy and for that part of the world, it is North Korea. They serve as the monster in that area,” Paul said.
