The Democratic People’s Republic of Korea (DPRK), known to the World as North Korea, has indicated that it has increased its ‘existing’ nuclear arsenal to counter a possible preemptive invasion by the United States. Earlier, the self-proclaimed nuclear power accused the United States of seeking to topple the government at the helm. It also feared that the joint US-South Korean military exercises could pose a preparatory war against the country. 

In recent times, North Korea’s and Iran’s nuclear adventurism has become so significant that important news was found missing from the current global strategic discourse on weapons of mass destruction (WMD). The news was concerning the acceptance by North Korea of the presence of bio-weapons in their country. The North Korean Vice Foreign Minister Kang Sok Ju has declared to Japanese sources, "Other than nuclear, we also have many other things. We also have bio-weapons.”
