Oblivion Pact by Don Pendleton

Hell on Earth

When a firefight breaks out in Mexico, the blitz leaves countless dead and Apache gunships in the hands of an Australian self-made millionaire and the soldiers of his white supremacist group. This in turn puts Mack Bolan in grim pursuit. Hijacking the ordnance turns out to be the first move in a campaign of terror that arms the enemy with an arsenal of experimental limpet mines. The killing sweep then strikes the Cayman Islands, with the object of stealing a supercomputer to control the limpets. And a deadly demonstration off the coast of Brazil leaves no doubt that World War III is the millionaire's ultimate goal.

Now all things from satellites to rockets are hands-on weapons of terror to cripple global defenses. Cities around the world will burn unless Bolan--using everything he's got--can dispatch the enemy into eternal darkness.
