The Executioner #460:

Omega Cult

written by Michael Newton, under the pseudonym Don Pendleton

North Korean terrorists unleash a devastating sarin-gas attack on Los Angeles: payback for US opposition to their homeland's nuclear expansion. With casualties mounting and fear of future strikes on the rise, Mack Bolan follows the trail of violence to the zealous billionaire funding the deadly campaign. Taking him outand saving thousands from an arsenal of suitcase bombs and biochemical weaponswill mean penetrating North Korea's treacherous border. But the Executioner's bloody pilgrimage won't end until he sends this scum straight into the afterlife.
