On Thursday, just hours after the UN passed tough sanctions on North Korea in response to the country’s recent nuclear test and long-range rocket launch, North Korea further escalated tensions by firing short-range missiles off its east coast.
It’s unclear how effective these sanctions will be; the behavior of North Korea’s government is unpredictable at the best of times, and past sanctions have hurt the vulnerable North Korean people as much as they’ve hurt the North Korean regime. 
So is there anything the UN, or any government, can do about North Korea? Check out the video below from Liberty in North Korea, where Dr. Sue Mi Terry, an expert on East Asia, explains US-North Korea relations and what can be done about North Korea.
