N Korea Military Tactics In A War With US

Third, North Korea’s total war plan has two components: massive conventional warfare and weapons of mass destruction.

If the US mounts a preemptive strike on North Korea’s Yongbyon nuclear plants, North Korea will retaliate with weapons of mass destruction: North Korea will mount strategic nuclear attacks on the US targets.

Nuclear weapons are offensive weapons and there is no defense against nuclear attacks except retaliatory nuclear attacks. For this reason, North Korea’s war plan is offensive in nature: North Korea’s war plan goes beyond repulsing US attackers and calls for destruction of the United States. Read entire Rense analysis.
