President Trump has been sending continuous love calls to North Korean leader Kim Jong Un, such as repeatedly posting photos taken with him. June 2019 at Panmunjom was the last time the two met... Will a fourth meeting actually take place?

Appearing on SBS Discovery of Knowledge, Dr. Cho Han-bum, a senior research fellow at the Korea Institute for National Unification, predicted that a US-North Korea summit is more likely to happen. He also outlined potential scenarios for what kind of agreement the leaders of the US and North Korea might reach if the summit takes place. If things unfold according to Dr. Cho's scenario, wouldn't a US-North Korea summit become problematic even if it is successfully held?
