"Let's assume that North Korea normalizes relations with the United States, why can't they then have military cooperation? After all, this is the best way to guarantee security of North Korea… Now relations between North Korea and the United States are hostile. If it is possible to improve these relations and these two countries can normalize them, then they can be transformed into a military partnership, if not an alliance," Moon said.
The official also assumed that the United States and North Korea would be able to exchange military information.
"Of course, this will happen if the United States has good relations with South Korea, North Korea and Japan. China may have some concerns, but if we are talking about military cooperation, China can take it with understanding," Moon added.
Joseph Yun, a former US special representative for North Korea, for his part, told Sputnik that it was currently impossible to imagine such military cooperation between Washington and Pyongyang.
After the first summit, held last year in Singapore, Trump said North Korea no longer posed a nuclear threat to the United States. The first US-North Korean summit resulted in an agreement stipulating that Pyongyang would make efforts to promote the complete denuclearization of the peninsula in exchange for the United States and South Korea freezing their military drills.
