Chemical weapons would almost certainly be deployed in any conflict.
Here's What You Need to Know: The deterioration of the conventional North Korean military makes the use of gas more likely than ever.
In recent years, North Korea’s chemical weapons have taken a backseat to her nuclear weapons. They are, however, no less dangerous. The deterioration of the Korean People’s Army (KPA) makes them more essential to victory than ever before. For both practical and doctrinal reasons, North Korea will almost certainly use chemical weapons in wartime, from riot control to lethal nerve gases.
Chemical weapons will be used to create a local, tactical advantage on the front lines and neutralize some advantages, such as air power. Thanks to North Korea’s prodigious missiles and artillery, they can be employed beyond the battlefield as well. North Korea will likely attack South Korea (ROK) through its depth with chemical weapons, from the Demilitarized Zone to Busan.
